Although the formation mechanism of biogenically metallic nanoparticles is broadly associated to enzyme mediation, major attention has been given to the role of proteins and peptides in oxido-reduction of metallic ions leading to these nanostructures. Among the wide range of biomolecules that can act not only as capping agents but also as non-enzymatic agents to form nanoparticles, disulphide bridge-containing...
Currently the need for various developmental models in material sciences to develop green technologies has been reemphasized. For biodiversity rich countries like India, low investment and sustainability of biological synthesis adds to its attraction. Plants respond to heavy metal stress by metal complexation process like production of phyochelations or by other metal chelating peptides. In this paper...
4-Mercaptobenzoic acid coated gold nanoparticles were used as Raman based labels in a standard immunoassay for mouse IgG. The Au nanoparticles used had a diameter of 51 ± 2 nm and were synthesised by the citrate reduction method. Dynamic light scattering and TEM image analysis were used to characterise the nanoparticles. The SERS spectra was recorded on an EZRaman desk-top spectrometer operating with...
