The sol–gel technology is being increasingly used for the development of optical sensors
and biosensors, due to its simplicity and versatility. By this process, porous thin films …

A large number of studies have been devoted to the development of chromic textile
materials because of their wide applicability as sensor systems. More recently, pH‐sensitive …

Nanofibres functionalised with pH-sensitive dyes could greatly contribute to the
development of stimuli-responsive materials. However, the application of biocompatible …

pH-sensitive chromic textiles are promising materials that can be used as flexible sensor
systems providing an easily visible signal. However to date, mainly conventional dyeing …

A highly selective optical sensor was developed for the Hg2+ determination by chemical
immobilization of 2-[(2-sulfanylphenyl) ethanimidoyl] phenol (L), on an agarose membrane …

It is of great interest to introduce pH-sensitive dyes into fibrous materials since this may
result in flexible sensor systems. However, to date, the effect of a textile matrix on the …

New fluorescent oxazolone derivatives with high two-photon absorption cross-section were
synthesized. Electron donor (phenyl, dimethylaniline and furanyl) and acceptor …

Sol-gel derived silica possess many promising features, including low-temperature
preparation procedure, porosity, chemical and physical stability. Applications exploiting …

Most of the fluorescent pH probes work near neutral or acidic regions of the pH scale. In this
work, two different fluorescent Schiff bases, chloro phenyl imino propenyl aniline (CPIPA) …

High efficiency orange and green emitting perylene dyes have been synthesized and
dispersed in an inert polymer host to form an optical downconversion layer. To avoid dye …
