This invention discloses an approach is improve the strength and reproducibility of the signal generated in FTAs using solid-phase microextraction (SPME) through the design of an approach to generate the plasmonically-enhanced signal for SERS, surface-enhanced infrared (SEIRA), and other enhanced spectroscopies. The design incorporates: (1) a particle-particle coupling strategy that is triggered by the selective capture of an analyte to a particle that has been immobilized on a membrane and has been modified to act as a capture substrate; (2) the selective tagging of the captured analyte by a nanoparticle also designed to generate an amplified plasmonic signal upon tagging; and (3) the incorporation of an internal nanoparticle standard to account for fluctuations in flow rates and flow paths. Collectively, these developments improve the accuracy and precision of the analysis as well as the SPME analysis accurately, improving the ease-of-use for a number of different SPME-based measurements, including, for example, those focused on disease markers using immunoassays and a range of other assay formats.

A chromogenic absorbent material for an animal litter includes an oxidizing agent responsive to peroxidatic/pseudoperoxidatic activity in an animal excretion or a first catalytic compound generating the oxidizing agent in situ. The material also includes a chromogenic indicator being chromogenically responsive to the oxidizing activity of the oxidizing agent, and an absorptive material which is porous, for absorbing the animal excretion. The absorptive material includes a water-absorbing polysaccharide providing absorptive properties to the chromogenic absorbent material; and may also include a second polysaccharide and a superabsorbent polymer. The material may be obtained in the form of particles having a low density and a high porosity, and is usable in conjunction with an animal litter for detecting various diseases in animals.
