Arsenic (symbol As, atomic number 33) is a group V-A, heavy toxic, ubiquitous element occurring in the atmosphere, soils and rocks, natural waters and organisms. Tripura is highly As prone area.
Recently at Thin Film and Nanoscience Laboratory, Tripura university we have designed a novel Fluorescence Resonance Energy Transfer (FRET)- based ratiometric sensor for detecting arsenic(v) with detection limit 10 ppb.
It was found that the proposed sensor is highly selective with respect to various salts (cations). The proposed method has also been tested using natural lake water and suitable results were obtained with good recovery, ranging between 95.1%–98.6% to the RSD value within range 0.5% −2.6%. The present system has also been tested with real As contaminated water.

Organic Nanostructures & Swithing:              To read the publication – click here

Recently we designed and synthesized as well as demonstrated the supramolecular assembly behavior of a 2,4,5-triaryl imidazole derivative at the air–water interface and in thin films using Langmuir–Blodgett (LB) technique. It has been demonstrated that this molecules form two types of nanostructures – Nanorod & Nanowire in thin films. These nanostructures were found to have switching behavior which may be promising for next-generation organic electronics.

Nanoscale aggregates onto ultra-thin films are gaining importance due to their potential applications towards opto-electronic device application.
Recently we have developed a series of aggregates (J aggregate/H aggregate/excimer etc) onto thin films via LB/LbL techniques. See list of publications: click here
