This book was released on 2020-09-17 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The routine measurement of significant physiological and biochemical parameters has become increasingly important for health monitoring especially in the cases of elderly people, infants, patients with chronic diseases, athletes and soldiers etc. Monitoring is used to assess both physical fitness level and for disease diagnosis and treatment. Considerable attention has been paid to electrochemical sensors and biosensors as point-of-care diagnostic devices for healthcare management because of their fast response, low-cost, high specificity and ease of operation. The analytical performance of such devices is significantly driven by the high-quality sensing interface, involving signal transduction at the transducer interface and efficient coupling of biomolecules at the transducer bio-interface for specific analyte recognition. The discovery of functional and structured materials, such as metallic and carbon nanomaterials (e.g. gold and graphene), has facilitated the construction of high-performance transducer interfaces which benefit from their unique physicochemical properties. Further exploration of advanced materials remains highly attractive to achieve well-designed and tailored interfaces for electrochemical sensing and biosensing driven by the emerging needs and demands of the “Internet of Things” and wearable sensors. Conducting polymers (CPs) are emerging functional polymers with extraordinary redox reversibility, electronic/ionic conductivity and mechanical properties, and show considerable potential as a transducer material in sensing and biosensing. While the intrinsic electrocatalytic property of the CPs is limited, especially for the bulk polymer, tailoring of CPs with controlled structure and efficient dopants could improve the electrochemical performance of a transducer interface by delivering a larger surface area and enhanced electrocatalytic property. In addition, the rich synthetic chemistry of CPs endows them with versatile functional groups to modulate the interfacial properties of the polymer for effective biomolecule coupling, thus bridging organic electronics and bioelectrochemistry. Moreover, the soft-material characteristics of CPs enable their use for the development of flexible and wearable sensing platforms which are inexpensive and light-weight, compared to conventional rigid materials, such as carbons, metals and semiconductors. This thesis focuses on the exploration of CPs for electrochemical sensing and biosensing with improved sensitivity, selectivity and stability by tailoring CP interfaces at different levels, including the CP-based transduction interface, CP-based bio-interface and CP-based device interface. First, we demonstrate different strategies for tailoring the physicochemical properties of poly (3,4-ethylenedioxythiophene) (PEDOT) beyond its intrinsic properties, via charge effects, structural effects and by the use of hybrid materials, as a CP-based transduction interface to improve sensing performance of various analytes. 1) A positively-charged PEDOT interface, and a negatively-charged carboxylic-acid-functionalised PEDOT (PEDOT:COOH) interface were developed to modulate the electrode kinetics for oppositely-charged analytes, e.g. negatively-charged nicotinamide adenine dinucleotide (NADH) and positively-charged dopamine (DA), respectively. These interfaces displayed high sensitivity and wide linear range towards the analytes due to the electrostatic attraction effect. 2) Various structured PEDOT including porous microspheres and nanofibres were synthesised via hard-template and soft-template methods, respectively, and were employed as building blocks for a hierarchical PEDOT and 3D nanofibrous PEDOT transduction interface, that facilitated signal transduction for NADH. 3) A PEDOT hybrid material interface was developed via using a novel bi-functional graphene oxide derivative with high reduction degree and negatively-charged sulphonate terminal functionality (S-RGO) as dopant to create PEDOT:S-RGO which delivered an enhanced electrochemical performance for various analytes. Based on the established CP-based transduction interface, biomolecules (e.g. enzymes) could be coupled to the CP surface to create CP-based bio-interfaces for biosensing. The immobilisation of enzyme was realised via either covalent bonding to a PEDOT derivative bearing a -COOH group (PEDOT-COOH) through EDC/NHS chemistry, or by physical absorption into the 3D porous PEDOT structure. The CP-based bio-interfaces were used to demonstrate the stable immobilisation of two different types of enzymes, i.e. lactate dehydrogenase and lactate oxidase, achieving the biosensing of analytes by relay bioelectrochemical signal transduction. Together, CP was employed as the CP-based device interface for the fabrication of a flexible and wearable biosensing device. A 3D honeycomb-structured graphene network was generated in-situ on a flexible polyimide surface by mask-free patterning using laser irradiation. The substrate was then reinforced with PEDOT as a polymeric binder to stabilise the 3D porous network by adhesion and binding, thus minimising the delamination of the biosensing interface under deformation and enhancing the mechanical behaviours for use in flexible and wearable devices. The subsequent nanoscale-coating of Prussian blue and immobilisation of enzyme into the 3D porous network provided a flexible platform for wearable electrochemical biosensors to detect lactate in sweat. Rutinmässig övervakning av hälsorelaterade fysiologiska och biokemiska parametrar har blivit allt viktigare för ett stort antal människor bland annat seniorer, spädbarn, patienter med kroniska sjukdomar, idrottare, soldater och med flera, på både en fysisk nivå för förebyggande av sjukdomar samt på en medicinsk nivå för diagnos och behandling av sjukdomar. Stor uppmärksamhet har lagts på utveckling av elektrokemiska sensorer och biosensorer som point-of-care (PoC) diagnostiska enheter for rutinmässig sjukvårdsledning genom deras snabba svar, låga kostnad, höga specificitet och enkla drift. Deras analytiska funktioner drivs av avkänningsgranssnittet vilket involverar signaltransduktion vid transducer-gränssnittet och effektiv koppling av biomolekyler till transducer-biogränssnittet för specifik analytigenkänning. Upptäckten av konventionella funktionella och strukturerade material, t.ex. metalliska nanopartiklar, kolnanorör och grafen, har underlättat konstruktionen av transducergränssnitt med hög prestanda på grund av deras unika fysiokemiska egenskaper. Ytterligare forskning av avancerade material ar önskvärt for att uppnå ett väldesignat och skräddarsytt gränsnitt for elektrokemisk avkänning och biosensering for Internet of Things och klädd sensorer. Ledande polymerer (LP) ar en typ av nya funktionella polymerer med extraordinär redoxomvändbarhet, elektronisk/jonisk ledningsförmåga och mekaniska egenskaper, som uppvisar betydande potential som ett givarmaterial vid avkänning och biosensering. Medan de inneboende elektrokatalytiska egenskaperna i LP:er är begränsade, speciellt for den skrymmande polymeren, kan skräddarsydda LP:er med kontrollerad struktur och effektiva dopmedel förbättra den elektrokemiska prestandan hos ett givargränssnitt med större ytarea och förbättrade elektrokatalytiska egenskaper. Dessutom ger den syntetiska kemin LP:er mångsidiga funktionella grupper för att modulera gränssnittsegenskaperna för LP:er för att förbättra selektivitet for analytdetektering, såväl som för effektiv biomolekylkoppling som ett biogränssnitt som överbryggar den organiska elektroniken och det biologiska system som stöds av de LP:s organkemiska natur. Dessutom möjliggör de mjuka materialegenskaperna för LP:er för användning i utveckling av en flexibla och bärbara avkänningsplattformar med låg kostnad och lätt vikt, jämfört med konventionella styva material, såsom metaller och halvledare. Denna avhandling fokuserar på utforskning av LP:er för elektrokemisk avkänning och biosensering med förbättrad känslighet, selektivitet och stabilitet genom att skräddarsy LP:s gränssnitt i olika nivåer, inklusive LP-baserat transduktionsgränssnitt, LP-baserat bio-gränssnitt och LP-baserat enhetsgränssnitt. Först demonstrerar vi olika strategier for att skräddarsy fysikalisk-kemiska egenskaper hos poly (3,4-etylendioxytiofen) (PEDOT) som ett LP-baserat transduktionsgränssnitt för avkänning via laddningseffekter, struktureffekter och hybridmaterialeffekter för förbättrad prestanda för olika analyser utöver dess inre egenskaper. 1) Ett positivt laddat hierarkiskt PEDOT-gränssnitt och ett negativt laddat karboxylsyra-funktionaliserad PEDOT (PEDOT: COOH) gränssnitt utvecklades for att modulera gränssnittets kinetik for de motsatt laddade analyterna, t.ex. negativt laddad s-Nicotinamidadeninudukleotid (NADH) respektive positivt laddat dopamin (DA). Den elektrokemiska avkänningsprestandan hos dessa analyser förbättrades baserat på laddningseffekten med högre känslighet och ett bredare linjärt intervall. 2) Med tanke på den väl skrymmande filmbildande egenskapen och den resulterande låga tillgängliga aktiva ytan för PEDOT, syntetiserades olika strukturerade PEDOT inklusive porösa mikrosfärer och nanofibrer via en hård mall respektive en mjuk mall och användes sedan som byggstenar för hierarkiska PEDOT och 3D nanofibrosa PEDOT-transduktionsgränssnitt, vilket underlättar signaltransduktion for NADH. 3) Ett LP-hybridmaterialgränssnitt utvecklades med användning av ett nytt bi-funktionellt grafenoxidderivat med hög reduktionsgrad och negativt laddad sulfonatterminal funktionalitet (S-RGO) med förbättrad elektrokemisk prestanda fär olika analyser. Baserat på det etablerade LP-baserade transduktionsgränssnittet utvecklades sedan de LP-baserade bio-gränssnitten med immobilisering av biomolekyler (t.ex. enzym) för biosensering. Immobiliseringen av enzym på LP-gränssnittet realiserades via antingen kovalent bindning till PEDOT-derivatbärande -COOH-grupper (PEDOT-COOH) genom EDC/NHS-kemi eller fysisk absorption i porösa 3D-PEDOT-strukturer. De LP-biobaserade gränssnitten visar stabil immobilisering av två olika typer av enzymer, d.v.s. laktatdehydrogenas och laktatoxidas, vilket uppnår biosensering av analyter genom en successiv bioelektrokemisk signaltransduktion. Tillsammans användes LP:er som det LP-baserade enhetsgränssnittet för tillverkning av en flexibel och bärbar biosenseringsanordning. Ett tredimensionellt bikakestrukturerat grafennatverk genererades in-situ på den flexibla polyimidytan genom maskfri mönstring med laserbestrålningsteknik. Substratet förstärktes sedan med nanodeponerat PEDOT som ett polymert bindemedel for att stabilisera det porösa 3D-nätverket genom vidhäftning och bindning, vilket sålunda förbättrade det mekaniska beteendet för flexibla och bärbara anordningar. Den sekventiella beläggningen på nanoskala av Preussiskt blått (PB) och immobiliseringen av enzym i det porösa 3Dnatverket minimerade delaminering av biosenseringsgränssnittet vid deformation, vilket försedde en flexibel plattform för en bärbar elektrokemisk biosensor för detektering av laktat i svett med det monterade treelektrodsystemet.
