WebNov 24, 2024 · To this end, a team led by Andrea Rentmeister chose to use a method known as photocaging. In this method, a “photocage” is a molecule that falls apart upon irradiation, such as a 2-nitrobenzyl group. The cage first blocks the target location, then targeted irradiation with light acts as a “switch” to remove the blockade. WebAug 1, 2024 · New photocaging groups that directly respond to NIR light via multiphoton events may be used for deep-tissue activation. Another frontier lies in using interdisciplinary approaches (e.g. nanomaterials and optogenetic constructs) to generate activating molecules (e.g. ROS and enzymes) by light to trigger existing chemocaging strategies.
