Protein encapsulation in complex coacervates as a function of charge density, sequence, and hydrophobicity.

Check out our new paper in @pubs.acs.org Biomacromolecules on "Tuning Protein Uptake through Charge and Hydrophobicity in Peptide-Based Complex Coacervates." You have built up your intuition about a phenomenon. . . and then surprising results happen. doi.org/10.1021/acs....

Happy #InternationalWomensDay!

So excited that Sarthak Saha was awarded the 2024 UMass Chemical and Biomolecular Engineering Best Dissertation Award for his research on "Advanced Microfluidics Platforms for Protein Crystallization and X-ray Crystallography"!

Complex Coacervate Emulsions as a Strategy to Stabilize Enzymes for Catalysis in Organic Solvents Complex coacervates have emerged as versatile platforms for protein encapsulation, enabling enzymatic catalysis in aqueous environments. Despite their potential, applications of coacervates are limite...

Happy #firstdayofschool! #LlabLlama

Check out the awesome new paper from our group, just published in Biomacromolecules (doi.org/10.1021/acs....)! We looked at sequence effects in peptide complex coacervates. In addition to phase behavior studies, we also identified some really cool rheological phenomena!

Looking for awesome #SciArt crafts? Check out this pattern for a needlepoint porcine parvovirus. Colors can be used to highlight different regions of a capsid surface.

Congratulations to Khiem Le on having defended his MS thesis on the Development of Automated Infrastructure in Microfluidics for Site-Specific Labeling of RNA! @umasschemeng.bsky.social

#LlabLlama is having a great time at the #EPF2025 in #Groningen, the Netherlands. Great polymer science, people, chocolate, and even a tiny bottle of bubbly!p

Great science presented today by Arvind and the rest of the group at @umassamherst.bsky.social Polymer Day!

Best wishes to the #Classof2025 graduated from Perry Lab! #LlabLlama

Congratulations @umasschemeng.bsky.social @umassengineering.bsky.social #Classof2025!!!

It was so great to have Northeastern Chemical Engineering Prof. Sara Hashmi for Polymer Science & Engineering seminar! Awesome work on complex flows in microfluidics, and #LlabLlama even got a shout out from Muffin and Peaches!

Research to Illuminate Protein Structure | UMass Amherst Chemical engineering major Yaozu Chen '25 creates microfluidics to determine the structure of proteins, a precursor to designing drugs to target certain proteins.

So proud of the work that @umasschemeng.bsky.social senior Yaozu Chen has done during his time in the group! Congratulations on winning the @umassamherst.bsky.social Rising Researcher Award!
