Plasmofluidic single-molecule surface-enhanced Raman scattering from dynamic assembly of plasmonic nanoparticles
Partha Pratim Patra,Rohit Chikkaraddy,Ravi P. N. Tripathi,Arindam Dasgupta,G. V. Pavan Kumar +4 more
TL;DR: By utilizing dual excitation of plasmons at metal-fluid interface, this work creates interacting assemblies of metal nanoparticles, which may be further harnessed in dynamic lithography of dispersed nanostructures and have implications in realizing optically addressable, plasmofluidic, single-molecule detection platforms.
Journal ArticleDOI
Single-Molecule Surface-Enhanced Raman Scattering Sensitivity of Ag-Core Au-Shell Nanoparticles: Revealed by Bi-Analyte Method.
TL;DR: By detecting resonant molecules at femtomolar concentrations, it is shown that Ag-core Au-shell nanoparticle can be harnessed for ultrasensitive detection of molecules and will further motivate usage of such gold-shell-based bimetallic nanostructures for SM-SERS in biological environments.
Journal ArticleDOI
Microbially-induced flocculation and flotation for pyrite separation from oxide gangue minerals
TL;DR: In this paper, it has been shown that pyrite can be separated from quartz and calcite through either selective flocculation or flotation after interaction with cells of B. polymyxa or bioproteins separated from the bacterial metabolite.
Journal ArticleDOI
Surface chemical studies on selective separation of pyrite and galena in the presence of bacterial cells and metabolic products of Paenibacillus polymyxa.
TL;DR: The effect of varying conditions for production of extracellular polysaccharides and protein provided an insight into the possible mechanism involved in microbially induced flocculation and flotation of pyrite and galena.
Journal ArticleDOI
Microbially induced flocculation and flotation for separation of chalcopyrite from quartz and calcite
TL;DR: In this paper, cells and metabolic products of Bacillus polymyxa were successfully used in flocculation and flotation to remove chalcopyrite from quartz and calcite with a view to environmental protection and ore beneficiation.
