Cellular Uptake and Antioxidant Activity of H2S-Releasing Tetrapeptide Supramolecular Polymer Nanostructures Self-assembled peptide–H2S donor conjugates (PHDCs) can deliver hydrogen sulfide in vitro and in vivo, yet the link between the supramolecular nanostructure morphology and cellular uptake remains unclear. Herein, we designed constitutionally isomeric PHDCs that self-assembled in aqueous solution into either nanoribbons, nanofibers, or nanobelts with various dimensions based on cryogenic transmission electron microscopy and small-angle X-ray scattering. Nile-red loaded PHDCs showed morphology-dependent uptake by H9C2 cells based on fluorescence microscopy combined with flow cytometry and confocal imaging, where narrow, helically twisted nanoribbons entered most efficiently. All PHDCs released H2S at similar rates, but the amount of H2S released inside the cells depended on the internalization ability of each PHDC. Consistent with these results, the narrow twisted nanoribbons afforded the greatest protection against H2O2-induced oxidative stress. Overall, this study highlights how subtle molecular-level changes can influence nanostructure formation in supramolecular assemblies and ultimately affect their cellular uptake and biological activities.

Brace yourself World! We have another new publication in hand! Congratulations to our dearest Dr. Zhao, Bushra, Ishani
and Clark for their paper in ACS Material Letters @pubs.acs.org in collaboration with Bitton group from @bengurionuni.bsky.social and Yin Wang! Hurray🥳

A BIG shout out to our awesome PMSE Best Undergraduate Student Poster judges. They came to #ACSFall2025 not only to discuss science but also to contribute to our community. Thank you! #science #chemistry #polymer #Students #Award @AmerChemSociety

This effort has been several years in the making, so we're excited that it is finally ready for public review. Please let us know what you think!

Travel to Malaysia begins today! Here I come #IUPAC2025 General Assembly and World Chemistry Congress. Looking forward to seeing many friends in iupacpolymer.bsky.social!

We are delighted to welcome Spencer Kearns over the summer as a part of VT's REU program. Spencer is senior at VT majoring in BS Chem. We look forward to experience some exciting research in polysaccharides from him soon!

Looking forward to having you join us in the @iupacpolymer.bsky.social as well!

Agreed! Great stuff #apme2025

Super excited to see this finally come out! Check out the fun TEM images. More are on the way!

Our undergrads Thomas, Deckland and Alex did a great job at the Undergraduates poster session in the HHS atrium today! We are super proud of their achievements and hard work !!

Sarah and I went to the Netherlands for her 2nd PhD defense! Now she has a PhD jointly awarded from @vtchemdept.bsky.social & @maastrichtu.bsky.social with a diploma the size of a large suitcase to prove it. Her 5 'opponents' put her through the ringer, but she came out victorious. Congrats, Sarah!

We enjoyed this collaborative work with groups from @vtchemdept.bsky.social and VT ChemE. Thanks to #GlycoMIP for funding and overall organization of our glycomaterials efforts!

Hi all, joining Bluesky today. Looking forward to discussions on #polymers, #chemistry, #H2S, #peptides, #biomaterials, and many other topics!
