"Programmed exosome fusion for energy generation in living cells"

Sumit Kumar et al.Nature Catalysis 4, 763–774 (2021)

The design of artificial organelles for applications in living cells faces several challenges such as cellular uptake, stability, and biocompatibility. Here, fusion of exosomes creates beneficial nanoreactors and their use for compartmentalized biocatalytic cascade reactions in cells is demonstrated. 

"Photoactive Antiviral Face Mask with Self-Sterilization and Reusability"

Sumit Kumar et al., Nano Letters 21, 1, 337–343 (2021)

We applied a dual-channel spray-assisted nanocoating hybrid of shellac/copper nanoparticles (CuNPs) to a nonwoven surgical mask, thereby increasing the hydrophobicity of the surface and repelling aqueous droplets. The resulting surface showed outstanding photoactivity for antimicrobial action, conferring reusability and self-sterilizing ability to the masks.


"Adaptive Architecture and Mechanoresponse of Epithelial Cells on a Torus", 

Sun-Min Yu et al., Biomaterials, 2021  265, 120420 

Our results collectively indicate the ability of epithelial cells to sense Gaussian curvatures and increase the expression of cytoplasmic and nucleus intermediate filaments as a protective measure against curvature-induced mechanical stress.
