In this project, we screened de novo designed protein libraries without natural ancestry for function, using #microfluidic droplets - and massively enriched short, truncated protein fragments. Turns out that these ≈ 40- to 60-residue fragments oligomerize to form a dynamic, catalytically proficient assembly, just as primordial peptides might have formed early enzymes during the prebiotic events that led to the #OriginOfLife! #ProteinEvolution

New single-cell analysis tech incorporates advanced fiber optics directly into microfluidic chips

Droplet microfluidics has revolutionized single-cell analysis, crucial for genomics, drug discovery, and diagnostics, by partitioning samples into nanoliter droplets for detailed cellular analysis. Yet, its broader adoption is hindered by the complex, costly methods required for analyzing droplets' optical properties.
