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.

Highly Sensitive Cuffless Blood Pressure Monitoring with Selective Laser‐Sintered Liquid Metal Conductors

open access: yesAdvanced Functional Materials, EarlyView.
A soft, compact, and cuffless system for continuous blood pressure monitoring using laser‐sintered liquid metal conductors is developed. The stretchability and sensitivity of the device enable real‐time, non‐invasive tracking of blood pressure, including recovery after exercise. This wearable device offers a practical solution for managing hypertension

Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces

open access: yesAdvanced Functional Materials, EarlyView.
The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...
