Nanofluidic iontronics, including the field-effect ionic diode (FE-ID) and field-effect ionic transistor (FE-IT), represent emerging nanofluidic logic devices that have been employed in sensitive analyses. Making analyte recognitions in predefined nanofluidic devices has been verified to improve the sensitivity and selectivity using a single ionic signal, such as ionic current amplification, rectification, and Coulomb blockade. However, the detection of analytes in complex systems generally necessitates more diverse signals beyond just ionic currents.

By a simple condensation reaction, the receptor with anthraquinone moiety was synthesized and its sensing properties were explored in the anion sensing studies via colorimetric, UV-vis studies, fluorescence studies, and DFT calculations. The synthesized receptor senses both acetate and hypochlorite ions in DMSO medium. By the addition of all anions into the receptor the colour change was observed from pink to light purple colour for acetate ion and pink to light blue for hypochlorite ion.

A new photopolymerizable organic-inorganic (O-I) hybrid sol-gel material, AUP@SiO-184, has been synthesized and utilized as a gate dielectric in flexible organic thin-film transistors (OTFTs). The previously reported three-arm alkoxy-functionalized silane amphiphilic polymer has yielded stable O-I hybrid materials comprising uniformly dispersed nanoparticles in the sol state. In this study, a photosensitizer was introduced, facilitating curing effects under ultraviolet light.

The early diagnosis of a disease relies on the reliable identification and quantitation of multiple core biomarkers in real-time point-of-care (POC) testing. To date, most of the multiplex photoelectrochemical (PEC) assays are inaccessible to home healthcare due to cumbersome steps, long testing time, and limited detection efficiency. The rapid and fast-response generation of independent photocurrent for multiple targets is still a great challenge.
