pH-Dependent depletion induced phase behavior of silica nanoparticles
Indresh Yadav,Vinod K. Aswal,Joachim Kohlbrecher +2 more
- 23 May 2017
TL;DR: In this article, the phase behavior of colloidal silica nanoparticles in the presence of bovine serum albumin (BSA) protein at different pH was studied, where the nanoparticles and BSA carry similar charges (negative) within the measured pH range, concomitantly the electrostatic repulsion prevents the adsorption of BSA on nanoparticles.
Tuning structure of oppositely charged nanoparticle and protein complexes
Sugam Kumar,Vinod K. Aswal,P. Callow +2 more
- 24 Apr 2014
TL;DR: In this article, the protein adsorption on nanoparticles is found to increase with pH and determined by the electrostatic attraction between two components as well as repulsion between protein molecules.

Additive-anchored thermoresponsive nanoscale self-assembly generation in normal and reverse Tetronics®.
Dhruv Patel,Payal Vaswani,Debes Ray,Dhiraj Bhatia,Vinod K. Aswal,Ketan Kuperkar,Pratap Bahadur +6 more
TL;DR: Self-assembly of star-shaped block copolymers in aqueous solution with additives leads to various micellar behaviors, including micelle formation/growth, micellar size reduction, and mixed micelle formation. The presence of salts, polyols, and ionic surfactants significantly affects the micellar behavior of the BCPs. Molecular interactions and hydrodynamic diameter (Dh) measurements are employed to understand the micellar structure and function. The additive-induced micellar systems are tested as nanovehicles for drug solubilization and cytotoxicity studies.

Studies on formation of star-shaped nanostructures in chitosan films induced by lithium salts
TL;DR: In this article, the effect of LiClO4 on the assembly of chitosan as star-like nanostructures has been investigated using various techniques that include X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), small-angle neutron scattering (SANS), and broadband dielectric spectrometer (BDS).
