Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

A Sustainable Biotechnology Approach for Mineral Separation

open access: yesAdvanced Functional Materials, EarlyView.
Silver‑binding peptides are first identified through phage‐display screening, and then engineered into multifunctional and responsive peptides or proteins. These tailored biomolecules can selectively capture and aggregate silver particles or ions from complex mixtures, enabling rapid and efficient silver separation and recovery.
