Introduction to Gold Nano Particles

What is/are Gold Nano Particles?

Gold Nano Particles - Therapeutic treatments like photo-imaging, gene delivery, drug delivery, cell labeling and photo thermal therapy   can be done by gold nano particles. ^[1] A novel fractal nano structures and Quantum dot (QD) arrays of gold Nano particles (NP) are introduced in this paper to enhance Strong absorbed radiation by nanoparticles then converted efficiently to heat by absorbed photon energy. ^[2] A simple and sensitive platform based on glassy carbon electrode (GC) and gold nano particles (AuNPs) was constructed for electrochemical determination of gabapentin (GB). ^[3] In the synthesis process, pre–synthesized spherical gold nano particles of 20-30 nm size served as nucleation sites for silver ions that formed coating over the gold core. ^[4] Low-temperature magnetic properties were investigated on the gold nano particles (GNPs) with an average size of 11. ^[5] This work aims at measuring experimentally proton induced secondary electron energy spectra after interaction with gold nano particles (GNPs) and polymer-coated GNPs. ^[6] While much effort has been devoted to elucidating the mechanisms behind bubble generation with spherical gold nano particles, the effects of particle shape on bubble generation thresholds are not well understood, especially in the nanosecond pulse regime. ^[7] Electrochemical properties of dopamine, uric acid and ascorbic acid have been investigated using gold nano particles (AuNPs) decorated functionalized multiwall carbon nanotubes (MWCNTs) nano composite modified electrode. ^[8] The Gold nano particles are electro-deposited on GCE. ^[9] new nano materials are engineered and designed that are suitable for medical implants and also silver and gold nano particles with anti-microbial properties) has come under great attention in recent times. ^[10]

Spherical Gold Nano Particles

In the synthesis process, pre–synthesized spherical gold nano particles of 20-30 nm size served as nucleation sites for silver ions that formed coating over the gold core. ^[1] While much effort has been devoted to elucidating the mechanisms behind bubble generation with spherical gold nano particles, the effects of particle shape on bubble generation thresholds are not well understood, especially in the nanosecond pulse regime. ^[2]
