Antibacterial activity of gold nanoparticles and their toxicity assessment
Methods The present study involved the synthesis of gold nanoparticles using a sodium cholate, as both reducing and capping agent and characterization by UVVisible spectroscopy and HighExpand
Facile Synthesis of Bile Salt Encapsulated Gold Nanoparticles and Its Use in Colorimetric Detection of DNA
A novel way to synthesize gold nanoparticles (AuNPs) using naturally occurring bile salts, namely, sodium cholate (NaC) and sodium deoxy cholate (NaDC), as reducing and capping agents at roomExpand
Synthesis of gold nanocluster-loaded lysozyme nanoparticles for label-free ratiometric fluorescent pH sensing: applications to enzyme–substrate systems and cellular imaging
This study developed a simple strategy to prepare lysozyme nanoparticle-encapsulated gold nanoclusters (LysNP-AuNCs) as a dual emission probe for ratiometric sensing of pH variation inExpand
Sodium cholate-templated blue light-emitting Ag subnanoclusters: in vivo toxicity and imaging in zebrafish embryos.
The survival and hatching experiment, no significant toxic effect was observed at AgNC concentrations of up to 200 μL/mL, and the NC-stained embryos exhibited blue fluorescence with high intensity for a long period of time, which shows that AgNCs are more stable in living system. Expand
Hierarchical Self-Assembly of Bile-Acid-Derived Dicationic Amphiphiles and Their Toxicity Assessment on Microbial and Mammalian Systems.
DCaC had potent antimicrobial activity and showed no toxicity on human RBCs indicating that DCaC could be used in biomedical applications, in addition to their industrial and laboratory applications such as detergency, surface cleaning, and disinfection agent. Expand
Label Free Fluorometric Characterization of DNA Interaction with Cholate Capped Gold Nanoparticles Using Ethidium Bromide as a Fluorescent Probe
This approach helped to understand the mode of interactions of DNA with cholate capped AuNPs without any modifications in a simple method and the results could be readout through the naked eye under the UV transilluminator. Expand
Oligonucleotide-Based Fluorescent Probe for Sensing of Cyclic Diadenylate Monophosphate in Bacteria and Diadenosine Polyphosphates in Human Tears
Cyclic diadenylate monophosphate (c-di-AMP) and P1,P5-diadenosine-5′ pentaphosphate (Ap5A) have been determined to play important roles in bacterial physiological processes and human metabolism,Expand
Biosurfactant templated quantum sized fluorescent gold nanoclusters for in vivo bioimaging in zebrafish embryos.
Abstract We report the biosurfactant (sodium cholate) templated bright bluish-green emitting gold nanoclusters (AuNCs) by green chemical approach. Optical properties of the AuNCs were studied usingExpand
