Modulation of Photophysics and pKa Shift of the Anti‐cancer Drug Camptothecin in the Nanocavities of Supramolecular Hosts
TL;DR: Steady-state, time-resolved fluorescence and electrospray ionisation mass spectrometry studies provide evidence for the formation of both 1:1 and 2:1 (CB7⋅CPT) stoichiometries, and docking and semi-empirical quantum chemical calculations have been employed to gain an insight into the molecular picture of orientation of CPT in the inclusion complexes.

TL;DR: The results suggest that Gua-IL forms a micellar kind of self aggregation above a certain concentration (≥1 mM), which instigates this compaction process of DNA, which is highly biodegradable and eco friendly in nature.
Comparative Study of Flavins Binding with Human Serum Albumin: A Fluorometric, Thermodynamic, and Molecular Dynamics Approach
TL;DR: These flavins are used as extrinsic fluorescence markers for probing the microheterogeneous environment of a well-known transport protein, human serum albumin (HSA), and it is confirmed that both FMN and FAD bind to the Sudlow's site-1 binding pocket of HSA, where Trp214 resides.

Cucurbit[7]uril assisted ultraviolet to visible fluorescence switch of a heart medicine
TL;DR: A novel fluorescence switch from ultraviolet (UV) to visible (cyan) is observed as a consequence of upward pKa shift of the drug inside the nano-cavity of cucurbit[7]uril.

How does the urea dynamics differ from water dynamics inside the reverse micelle
TL;DR: Time-resolved fluorescence anisotropy study confirms the existence of a confined environment around the dye at higher concentrations of urea inside the reverse micelle and observes that with the increase in urea concentration, the overall dynamics becomes slower, and it infers the presence of few water or urea molecules.
