Förster transfer in coupled colloidal type-II and type-I quantum dots

Mourokh L.G., Kuskovsky I.L., Smirnov A.Yu., Matsui H., Queens College, CUNY, US

We examine theoretically resonant non-radiative exciton (Förster) transfer in the system of colloidal core-shell quantum dots (QDs) of different types. In this, the type-II QDs with electrons and holes separated in the real space have [...]

Surface Plasmon Spectral Shifts of Functionalized Gold Nano particles for the Use in Biosensors

Chatterjee S., Moriarty G., Gersten B., Queens College, CUNY, US

Recently there has been interest in the use of gold nanoparticles as a colorimetric method to detect the hybridization event of DNA [1-4]. The method uses the physical phenomena that nanoparticles of gold exhibits the [...]

Molecular Dynamics Simulation of a Single Stranded (ss) DNA

Chatterjee S., Gersten B., Thakur S., Burin A., Queens College, CUNY, US

The objective of this study was to develop an understanding of the essential physical properties of short-single stranded DNA (ssDNA) towards the development of new DNA based biosensors. To achieve this goal, various thermodynamic properties [...]

Towards the Preparation of Boron Carbide Nanorods by Carbothermal Reaction Method

Chang B., Gersten B.L., Szewczyk S.T., Adams J.W., Queens College, CUNY, US

Boron carbide (B4C) is an attractive material due to its extreme hardness, low specific weight, high chemical stability and good wear resistance. In this study, nano-sized boron carbide powders have been prepared through a carbothermal [...]
