Preparation of Gold Nanoparticles Using Tea: A Green Chemistry Experiment

Assimilating green chemistry principles in nanotechnology is a developing area of nanoscience research nowadays. Thus, there is a growing demand to develop environmentally friendly and sustainable methods for the synthesis of nanoparticles that utilize nontoxic chemicals, environmentally benign solvents, and renewable materials to avoid their adverse effects. A simple, economic, and environment...

Amine-gold linked single-molecule circuits: experiment and theory.

A combination of theory and experiment is used to quantitatively understand the conductance of single-molecule benzenediamine-gold junctions. A newly developed analysis is applied to a measured junction conductance distribution, based on 59 000 individual conductance traces, which has a clear peak at 0.0064 G0 and a width of +/-47%. This analysis establishes that the distribution width originat...

Discrete Dipole Approximation simulations of gold nanorod optical properties: choice of input parameters and comparison with experiment

Gold nanorods have interesting optical properties due to surface plasmon resonance effects. A variety of biomedical applications of these particles have been envisaged and feasibilities demonstrated in imaging, sensing and therapy based on the interactions of light with these particles. In order to correctly interpret experimental data, and tailor the nanorods and their environments for optimal...

Determination of the Optical Properties of Individual Gold Nanorods Through Numerical Modelling and Experiment

The optical scattering and absorption of gold nanorods (GNRs) depends on its size, shape, and surroundings. This dependence is due to both intrinsic and extrinsic effects. A good understanding of this dependence is needed for applications of GNRs in photo-thermal therapy, optical and opto-acoustic imaging, biosensing, and other photonic areas. Extrinsic effects are caused by the production of l...
