Quantized conductance observed during sintering of silver nanoparticles by intense terahertz pulses [PDF]
Applied Physics Letters, vol. 112, no. 16, p. 163102 (2018), 2018 We show that silver nanoparticles, which are deposited on a terahertz-receiving antenna, can be sintered by intense terahertz pulse irradiation. The conductance of the silver nanoparticles between the antenna electrodes is measured under the terahertz pulse irradiation.

Pharmaceutical aspects of silver nanoparticles [PDF]
Artificial Cells, Nanomedicine, and Biotechnology, 2017 Silver nanoparticles are particles in the size ranging between 1 and 100 nm. The two major methods used for synthesis of silver nanoparticle are the physical and chemical methods with the disadvantage that they are expensive and can also have toxicity. Biological method is being used as an expedient alternative, as this approach is environment-friendly
