Book excerpt: Optical sensors have attracted a lot of interest due to their increased performance and ability to perform chemical identification through spectroscopy. Integrated sensors present the additional advantages of compactness and increased light-matter interactions. This thesis aimed at advancing the field of photonic sensing by demonstrating novel devices and applications, and improving the performance of current sensors. In particular, we studied flexible integrated photonic sensors and substrates for surface-enhanced Raman spectroscopy. We first propose and demonstrate a three-dimensional flexible photonic sensor array for stress mapping in soft materials systems such as cell cultures. Our device relies on stress-optical coupling to infer stress from optical measurements and uses a deterministic 3-D fabrication method to precisely position the sensors in space. We characterized the sensors’ response to mechanical stimulation by measuring their strain-optical coupling coefficient. Our device is amenable to measuring strains down to 0.001% or forces down to 1 nN in any matrix with a modulus greater than 300 Pa, with a spatial resolution of 100 μm, enabling the detection of the effects of about a dozen cells. Overall, our device provides fast, easy, and precise measurements even in opaque samples, in a greater range of volumes and geometries than previously available. More broadly, this platform prefigures the ability to perform multifunctional sensing and light delivery in three dimensions. In addition, we look at the efficiency of surface-enhanced Raman spectroscopy (SERS), a popular spectroscopy technique with a broad range of applications. Using a reasoning based on the local density of states (LDOS), we derived a limit for the enhancement provided by nanoantennas, which is shown to include factors relating to the antenna’s material and to the antenna’s geometry. We then simulated the response of typical structures and found that they lie several orders of magnitude away from the bound. In the case of spheres, we showed that periodic structures can outperform isolated structures only under certain geometrical conditions. This study paves the way for the definition of performance metrics that can be used for further optimization of SERS substrates.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, sensor research has undergone a quiet revolution that will have a significant impact on a broad range of applications in areas such as health care, the environment, energy, food safety, national security, and manufacturing. Sensors for Chemical and Biological Applications discusses in detail the potential of chemical and biological sensors and examines how they are meeting the challenges of chem-bio terrorism by monitoring through enhanced specificity, fast response times, and the ability to determine multiple hazardous substances. Exploring the nanotechnology approach, and carrying this theme throughout the book, the chapters cover the sensing principles for, chemical, electrical, chromatographic, magnetic, biological, fluidic, optical, and ultrasonic and mass sensing systems. They address issues associated with cost, synthesis, and testing of new low cost materials with high sensitivity, selectivity, robustness, and speed for defined sensor applications. The book extensively discusses the detailed analysis of future impact of chemical and biological sensors in day-to-day life. Successful development of improved chemical sensor and biosensor systems and manufacturing procedures will not only increase the breadth and depth of the sensor industry, but will spill over into the design and manufacture of other types of sensors and devices that use nanofabrication and microfabrication techniques. This reference not only supplies versatile, hands-on tools useful in a broad array of disciplines, but also lays the interdisciplinary groundwork required for the achievement of sentient processing.

Available in PDF, EPUB and Kindle. Book excerpt: With their similarity to the organs of the most advanced creatures that inhabit the Earth, sensors are regarded as being the “senses of electronics”: arti?cial eyes and ears that are capable of seeing and hearing beyond the range of - man perception; electronic noses and tongues that can recognise odours and ?avours without a lifetime training; touch that is able not only to feel the texture and temperature of the materials but even to discern their chemical compo- tion. Among the world of chemical sensors, optical devices (sometimes termed “optodes”, from the Greek “the optical way”) have reached a prominent place in those areas where the features of light and of the light-matter interaction show their advantage: contactless or long-distance interrogation, detection sensitivity, analyte selectivity, absence of electrical interference or risks, and lack of analyte consumption, to name just a few. The introduction of optical ?bres and integrated optics has added more value to such sensing since now light can be con?ned and readily carried to dif?cult-to-reach locations, higher information density can be transported, indicator dyes can be immobilised at the distal end or the evanescent ?eld for unique chemical and biochemical sensing (including multiplexed and distributed measurements), optical s- sors can now be subject to mass production and novel sensing schemes have been established (interferometric, surface plasmon resonance, ?uorescence energy transfer, supramolecular recognition . . . ).
