Journal ArticleDOI
Body- or tip-controlled reactivity of gold nanorods and their conversion to particles through other anisotropic structures
TL;DR: The shape transformation of gold nanorods to spherical nanoparticles, assisted by cupric ions is reported, and it is shown that the body of the rods is more susceptible for reaction at reduced CTAB concentrations.
Journal ArticleDOI
Reversible assembly and disassembly of gold nanorods induced by EDTA and its application in SERS tuning.
TL;DR: TEM analysis proved the existence of end-to-end chains at lower concentrations of EDTA and side-by-side assembled sheet-like structures at higher concentrations, and showed that the disassembly involves the formation of bundled chains which may be the reason for the observed spectral changes.
Journal ArticleDOI
Solar mediated reduction of graphene oxide
Manonmani Mohandoss,Soujit Sen Gupta,Anith Nelleri,Thalappil Pradeep,Shihabudheen M. Maliyekkal +4 more
TL;DR: In this article, the reduction of water dispersed graphene oxide (GO) by sunlight as an environmentally friendly alternative to conventional methods of reduction of GO was explored and the possible mechanism of the reduction process was delineated.
Journal ArticleDOI
Solvothermal synthesis of silver nanoparticles from thiolates
M. J. Rosemary,Thalappil Pradeep +1 more
TL;DR: A new solvothermal method for the synthesis of thiol-protected silver nanoparticles starting from silver thiolates is reported, and the particle size was found to be nearly the same for both molecules.
Journal ArticleDOI
Protein-encapsulated gold cluster aggregates: the case of lysozyme
Ananya Baksi,Paulrajpillai Lourdu Xavier,Kamalesh Chaudhari,Nirmal Goswami,Samir Kumar Pal,Thalappil Pradeep +5 more
TL;DR: Time dependent studies reveal the emergence of free protein and the redistribution of detached Au atoms, at specific Lyz to Au(3+) molar ratios, as a function of incubation time, proposing inter-protein metal ion transfer.
