Lipid nanoparticles (LNPs) are a leading platform for mRNA delivery, yet improving their performance often requires complex chemical modification or reformulation of core components. Here, we report a modular peptide-coating strategy for post-formulation engineering of LNP interfaces through physical assembly. A modu...

Efficient and safe delivery of nucleic acids remains a major challenge for clinical translation of gene therapies. Here, we report de novo-designed α-helical peptides that coassemble with lipids and nucleic acids to form core-shell, virus-like nanoparticles (VLNs). The peptides combine a cationic N-terminus for nucleic...

We report the rational engineering of a two-α-helix protein via site-directed mutagenesis, wherein histidine residues at the native catalytic active site were substituted with cysteines and tyrosine residues were introduced in close proximity to these cysteine residues. This modification enabled the site-directed red...

It is demonstrated that the catechol-nanocellulose/chitosan polymeric hydrogel effectively overcomes adhesion, infection, and oxidative stress barriers in diabetic wound healing, making it a promising candidate for difficult-to-heal chronic ulcers.
The accumulation of poly(ethylene terephthalate) (PET) waste in the environment poses a severe ecological threat. While extensive research has focused on high-performance PET degradation by thermophilic enzymes, PET hydrolases are efficient under lower-temperature conditions, which would better align with green and ene...
