This project revolves around the design and implementation of floating point adder architecture using reversible logic to improve the design in terms of the number of garbage outputs and the number of gates used. In recent years, reversible logic has emerged as a promising technology having its applications in low power CMOS, quantum computing, nanotechnology and optical computing because of it...

In spite of the substantial amount of work done in optical sensor research, it is difficult to find a biochemical receptor/optical transducer scheme, which can be used for a device permitting the continuous monitoring of a chemical compound in clinical or environmental samples. Perhaps one of the most interesting alternatives is based on using biochemical receptors that, in the appropriate conc...

An elegant method is proposed and demonstrated for tracking the location and movement of nanoparticles in an optical microscope using the optical phenomenon of caustics. A simple and reversible adjustment to the microscope generates caustics several orders of magnitude larger than the particles. The method offers a simple and relatively inexpensive method for visualizing such phenomena as the f...

Selective ligands are lacking for many neuronal signaling proteins. Photoswitched tethered ligands (PTLs) have enabled fast and reversible control of specific proteins containing a PTL anchoring site and have been used to remote control overexpressed proteins. We report here a scheme for optical remote control of native proteins using a "photoswitchable conditional subunit" (PCS), which contain...

In recent years, reversible logic has emerged as a promising computing paradigm having its applications in low power computing, quantum computing, nanotechnology, optical computing and DNA computing. The classical set of gates such as AND, OR, and EXOR are not reversible. Recently, it has been shown how to encode information in DNA and use DNA amplification to implement Fredkin gates. Furthermo...

We theoretically predict that a dielectric nanofilm subjected to a normally incident strong but ultrashort (a few optical oscillations) laser pulse exhibits deeply nonlinear (nonperturbative) optical responses which are essentially reversible and driven by the instantaneous optical field. Among them is a high optical polarization and a significant population of the conduction band, which develo...
