Spiropyran containing polymer brushes were used as reversible, photoswitchable optical sensors that show selectivity for different metal ions and drastic changes in surface wettability.

Reversible fluorescence quenching and anti-quenching of CdS quantum dots immobilized in boronic acid-based microgels can be used for the optical detection of glucose.

Reversible logic circuits have received significant attention in quantum computing, low power CMOS design, optical information processing, DNA computing, bioinformatics, and nanotechnology. This paper presents two new 4× 4 bit reversible multiplier designs which have lower hardware complexity, less garbage bits, less quantum cost and less constant inputs than previous ones, and can be generaliz...

Reversible circuit designing is the area where researchers are focussing more and more for the generation of low loss digital system designs. Researchers are using the concept of Reversible Logic in many areas such as Nanotechnology, low loss computing, optical computing, low power CMOS design etc. Here we have proposed a novel design approach for a 2-bit binary Arithmetic Logic Unit (ALU) usin...

A porphyrin-based amphiphile that exhibits various self-assembled nanostructures in different solvents has been successfully prepared. The effect of aggregated structure on optical properties of this amphiphile has been well investigated. Furthermore, this porphyrin-based amphiphile and its assemblies show dynamic/reversible variations in morphology and optical properties in response to light.

Biomedical optics and photomedicine applications are challenged by the turbidity of most biological tissue systems. Nonreactive, biocompatible chemical agents can induce a reversible reduction in optical scattering of collagenous tissues such as human skin. Herein we show that a chemical agent's tissue optical clearing potential is directly related to its collagen solubility, providing a ration...

We introduce here a dynamic optode for buffer capacity sensing based on photochromic spiropyran (Sp). It represents the first reversible optical sensor for buffer capacity. Sensing was possible using a non-equilibrium readout mode, a novelty for photoswitchable optical ion sensors. In addition to the buffer capacity, the final point of each measurement sequence provides the pH of the solution.

A facile method for achieving optical switching of the Dirac point and conductance in reduced graphene oxide multilayer FETs that are non-covalently functionalized with a photo-responsive spiropyran derivative is presented. The photoresponsive transition from spiropyran to merocyanine induces the reversible optical switching in graphene based FETs.
