Tailored Organogel Systems for Optimized Pesticide Delivery: Mechanistic Insights and Agricultural Applications

open access: yesAdvanced Science, EarlyView.
Utilizing molecular engineering for network design, three pesticide‐loaded organogels (PLOs) carriers exhibiting varying degrees of flexibility were prepared. The mechanical properties of these carriers, tunable via their network molecular structures, enhance their structural adaptability and retention stability at biological interfaces, thereby ...

Multi‐Targeting Non‐Specific Genome Engineering in Bacteria

open access: yesAdvanced Science, EarlyView.
In this study, we provide the first case to use the multi‐targeting integrase (MTI) systems in bacteria and develop a host‐independent generalizable approach, MNGE (Multi‐targeting Non‐specific Genome Engineering), for multi‐copy and random integration of metabolic genes or pathways in both Gram‐positive and Gram‐negative bacteria, which will ...
