Nano Approaches to Nucleic Acid Delivery: Barriers, Solutions, and Current Landscape

open access: yesWIREs Nanomedicine and Nanobiotechnology, Volume 17, Issue 2, March/April 2025.
Nano approaches for breaking barriers to nucleic acid delivery. ABSTRACT Nucleic acid (NA) therapy holds tremendous potential for treating a wide range of genetic diseases by the delivery of therapeutic genes into target cells. However, significant challenges exist in safely and effectively delivering these genes to their intended locations.

Photocatalytic Semi‐Hydrogenation of Acetylene to Polymer‐Grade Ethylene with Molecular and Metal–Organic Framework Cobaloximes

open access: yesAdvanced Materials, Volume 37, Issue 1, January 8, 2025.
Novel photocatalytic systems based on homogeneous and heterogeneous cobaloximes are reported. By leveraging their hydrogen atom transfer catalytic activity, exquisitely efficient and selective acetylene photocatalytic semi‐hydrogenation is reported. Integrating the cobaloximes in a metal–organic framework results in more stable and durable catalysis ...
