MicroAnalytical Systems (µAS) adapted to Point-of-Care Testing are expected to provide simple chemical, molecular or cellular analysis to be used directly on the field. Different formats of µAS are already classically used, from pregnancy tests to glycemia for diabetic people. Increasing µAS analytical performances involves for instance improving limits of detection, reduce time of analysis, or increase the amount of information provided per test. These improvements may be reached by using more refined technology, involving integrated technologies such as biosample processing, enzymatic reactions, fluidic circuitry and/or biosensors. However being able to fabricate and produce cheap µAS relying on miniaturized components is still a challenging goal, particularly when dealing with low concentrated species. For example, on the one hand it may be interesting to use miniaturize nanotransducers in biosensors (e.g. photonic transducer enabling both SPR and SERS thanks to nanostructuration) ; but on the other hand the transducers size reduction may prevent the targets to reach the biosensor’s active zone in a short time, because of mass transfer phenomena. Futhermore, when the sensing area is small by comparison with the other µAS zones, it targets are likely to get adsorbed on undesired surfaces. These targets are therefore lost and cannot contribute to the final, useful signal of the µAS. In these conditions the effectivity of the µAS can be questionned. Different ways are being explored to overcome such challenges, and may enable µAS for detection of low concentration targets. For instance, it is possible to perform selective chemical modifications of surfaces bearing different materials, in order to bind molecular probes only on the transducing zone, while repelling molecular targets from other material surfaces. We will show how it is possible to perform such orthogonal surfaces modifications with a submicronic spatial resolution, relying on self-assembly phenomena.

Point-of-care tests (POCT) are important for detecting illnesses and monitoring patients without the need of a medical laboratory. To be useful, POCT must be sensitive, specific, integrated, and affordable. Since the early 2000s, integrated photonics have offered a possible solution for this problem. In particular, silicon micro-ring resonators represent a compact and sensitive choice known in the industry. This paper details the design, fabrication, and characterization of two methods for improving the performance of ring resonators by engineering their cross section. More precisely, improving devices made out of silicon nitride in an industrial environment to work in the infrared (around 1.31 µm). The first approach is to selectively excite the first order mode of the ring resonator’s waveguide. The first order mode, with its greater exposure to the sensing liquid than the fundamental mode, results in a higher device sensitivity. The second method consists in coupling a dielectric mode with a surface plasmon polariton (SPP) forming a hybrid plasmonic waveguide. Hybrid plasmonic waveguides combine the low losses of the dielectric mode with the high sensitivity of the SPP, which increases the sensitivity in comparison to conventional dielectric ring resonators. Furthermore, hybrid plasmonic micro-ring resonators make possible a stable and easy differential functionalization. Through the optical characterization of the devices, this study shows an experimental sensitivity of first order ring resonators of over 200 nm/RIU* and of hybrid plasmonic devices of 300 nm/RIU*. This demonstrates improvement with respect to the reference silicon nitride dielectric ring (120 nm/RIU*). Characterizations were performed using a PolyDiMethylSiloxane (PDMS) fluidic system to prove the compatibility of the substrate to POCT applications. This paper shows two alternative approaches to integrated nano-photonic sensing for point of care testing. The proposed structures, demonstrate not only a higher sensitivity, but consider selectivity and manufacturing issues, which are fundamental for POCT development. *RIU = Refractive Index Unit

Experimental data and modeling of X(2) temporal stability of poled chromophore-doped sol-gel materials

The relaxation of the second-order nonlinearity of poled chromophore-doped sol-gel thin films has been studied at different temperatures between 63 degree(s)C and 82 degree(s)C (poling temperature: 90 degree(s)C). The process has been monitored through the variations of second harmonic generation (SHG) induced in the poled film by a pulsed nanosecond Nd:YAG laser (1064 nm). The SHG decay curves have then been fitted to bi-exponentials and Kohlrausch, Williams and Watts (KWW) stretched exponentials. The better quality of the KWW fits involves that this model is more appropriate than the bi- exponential model to describe chromophore relaxation in sol- gel thin films, as has been observed for classical all- organic polymers. A numerical analysis of the KWW parameters enables a better understanding of the function meaning. The time constants obtained with both models have been logarithmically plotted in function of temperature. An Arrhenius-type linear fit has been adjusted to this representation, and a value of the relaxation time extrapolated at room temperature. The bi-exponential model yields time constants of 26 and 110,000 years, while the KWW model extrapolates to an 87 years' second-order nonlinearity lifetime with a corresponding activation energy of 49 kcal.mol^-1. Decay data gathered at room temperature over a period of 17 months can be fitted with both models and yield time constants of 14 days and 13 years for the bi- exponential, and of 115 days for the stretched exponential. The extrapolated KWW fit can be corrected with a factor of 0.58 to adjust the experimental data. This reveals the possible existence of a very rapid relaxation (less than a minute for our measurement temperatures) that was not measured. Nonetheless, our work shows that second-order nonlinearity in poled chromophore-doped sol-gel thin films is stable for more than a year. This is an encouraging result for future applications in telecom industry, especially as this feature has not yet been studied and optimized in terms of material synthesis.

We optically functionalized transparent hybrid matrices prepared by the sol-gel process by doping them with organic chromophores. Highly dense and chemically stable bulk and film materials of good optical quality have been synthesized in this way. Such materials can exhibit very different optical properties, depending on the choice of the chromophores and the type of environment provided by the sol-gel matrices. On one hand, the optical properties conferred to the solid state material can be those for which the dyes have been known and optimized in solution; this is, for example, the case of solid state dye lasers which performances have dramatically improved over the past few years, from the possibility of emitting 1,000s of microjoules pulses to 1,000,000s of millijoule pulses, illustrating the huge optimization potential of this material synthesis route strong reverse saturable absorption for optical limiting applications. . . On another hand, new properties can be demonstrated in the solid form, in particular, due to the restricted motion of the dopants in rotation and translation; that is the case of all optical memory, of second order nonlinear activity ((chi) ⁽²)), and, most recently, photorefractivity. We will especially detail the photorefractive properties of new media based on hybrid organic-inorganic materials containing charge transporting molecules and second order nonlinear optical chromophores introduced as side-chain units. These materials, prepared by the sol-gel process in the form of few micrometers thick films, were studied by two beam coupling (2BC), electronic absorption, electro-optic and photoconductivity experiments. The presence of a strong static electric field (30 V/micrometers ) inside poled films was evidenced, and can explain the photorefractive properties obtained without applying any external electric field. Finally, one common issue all organic-based materials have to solve to take advantage of their high efficiencies and have potential applications outside the laboratories, is the chromophore photodegradation which limits the operational lifetimes of devices made from such materials. This point is under investigation and initial results show that the quantum efficiencies of these photoinduced chemical reaction can vary by several orders of magnitude, within this class of hybrid materials.

Organic dye molecules have been widely used in solution as amplifying media in tunable lasers. The possibility of trapping these molecules in a solid state matrix may lead to a new field of application outside the laboratory. Many types of matrices can be used. We present results with new hybrid organic/inorganic xerogels prepared by hydrolysis-condensation of the methyl- or vinyl-triethoxysilane precursor under acid-catalyzed hydrolysis and basic-catalyzed condensation. Organic methyl or vinyl groups attached to the silica network provide a favorable environment to dye fluorescence. We have studied the effect induced by using different basic catalysts: N-(2-aminoethyl)-3-aminopropyltrimethoxysilane and 3- aminopropyltriethoxysilane are found to lead to the best matrix characteristics. Perylenes and pyrromethenes were chosen because of their thermal- and photo-stability. After gelation, 10 mm thick samples, polished to a surface roughness of about 4 nm, are placed in a plano- concave cavity as gain media and pumped by a frequency doubled nanosecond Q:switched Nd:YAG laser. Efficiency is the greatest with a pyrromethene 597 doped sample: more than 6 mJ output energy for a 10 mJ pump energy (2 J/cm² fluence) leading to a slope efficiency of 63%. The lifetime of the laser emission when the same point of the sample is sequentially used is also an important characteristic. Best results are obtained with perylene red dye: for a pump energy of 0.7 mJ at 1 Hz repetition rate, the output energy is still 50% of the initial value (0.1 mJ) after 80,000 shots. For a pyrromethene 597 doped MTEOS sample, it appears that the measured lifetimes are independent of the operating frequency in the 0.2 - 20 Hz range, indicating a reasonable heat conductivity for this type of matrix. We have also studied tunability by adding a grating or prism to the cavity: a typical tunability of over 50 nm or more is obtained with many of these dyes. Finally we report laser activity obtained with rhodamine B doped xerogels in which the dye molecules were covalently bonded to the silica network in order to stabilize the organic molecule structure.
