Optically sensing phospholipid induced coil–helix transitions in the phosphoinositide-binding motif of gelsolin
A FRET-based probe reveals that coil–helix transitions in the phospholipid binding sequence of gelsolin occur at physiological phosphatidylinositol-4,5-bisphosphate concentrations.
Optical backbone-sidechain charge transfer transitions in proteins sensitive to secondary structure and modifications
We report the UV-vis absorption originating from protein backbone-sidechain charge transfer transitions in charged amino acids with anionic and cationic sidechains.
Controlling anticancer drug mediated G-quadruplex formation and stabilization by a molecular container
G-quadruplex DNA (GQ-DNA) formation has been controlled using a molecular container, cucurbituril (CB7), by means of translocating a potential anticancer drug, topotecan, from GQ-DNA to the CB7 nanocavity. Interestingly, this whole cycle can be easily monitored through the change in the emission color of the stabilizing ligand, i.e., topotecan.
Enhanced fluorescence with nanosecond dynamics in the solid state of metal ion complexes of alkoxy salophens
Incorporation of an alkoxy moiety dramatically alters the photophysics and molecular packing of aluminum complexes of salophen leading to enhanced emission in the solid state.
Conformational and hydration properties modulate ice recognition by type I antifreeze protein and its mutants
Mutation of wfAFP changes the intrinsic dynamics in such a way that it significantly influences water mediated AFP adsorption on ice.
Packing energetics determine the folding routes of the RNase-H proteins
The RNase-H proteins show a diverse range of folding routes with structurally distinct folding nuclei.

The folding/unfolding equilibrium of proteins in aqueous medium can be altered by adding small organic molecules generally termed as co-solvents.
Bifunctional Ru(II) complex catalysed carbon–carbon bond formation: an eco-friendly hydrogen borrowing strategy
Bifunctional Ru(II) complex (0.1 mol%) catalysed one-pot β-alkylation of secondary alcohols with primary alcohols and double alkylation of cyclopentanol were carried out successfully following the atom economical borrowing hydrogen methodology.
Tracer diffusion in a sea of polymers with binding zones: mobile vs. frozen traps
We simulate tracer dynamics in a sea of polymers with binding zones and address the issue of non-Gaussianity.
Exploration of the presence of bulk-like water in AOT reverse micelles and water-in-oil nanodroplets: the role of charged interfaces, confinement size and properties of water
We show that the distance from the interface at which bulk-like properties are recovered strongly depends on the choice of order parameter being probed: translational < tetrahedral ≪ dipolar orientation.
