Characterization of 2PA of DNA-stabilized silver nanoclusters (Ag_N-DNAs) with far-red to NIR emission identify them as water-soluble two-photon absorbers.

Ligand-directed chemistry (LDchem) sialyltransferases (ST) probes with an O-nitrobenzoxadiazole warhead enable selective fluorescent labelling of a wide range of recombinant STs and native lipooligosaccharide ST (Lst) in Neisseria gonorrhoeae.

Thiosemicarbazones exhibit versatile photochromic and supramolecular properties, making them excellent photoswitches for designing systems that respond to external stimuli.

Developing a self-sensitized catalyst from earth-abundant elements capable of efficient light harvesting and electron transfer is crucial for enhancing the efficacy of CO₂ reduction, environmental cleanup, and improving clean energy prospects.

We computationally investigated the fragmentation pathways of saturated molecules detected in the interstellar medium, demonstrating how high-energy processes drive their transformation into unsaturated species with extended π-bond networks.

We have demonstrated the synthesis of regio- and diastereoselective cyclobutylated phenothiazines via [2 + 2] visible-light-irradiated cycloaddition and wavelength-gated cycloreversion inside the live cells for cell imaging and drug delivery.
