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. http://zwzz.chinacrops.org/article/2024/1001-7283/1001-7283-39-2-16.shtml
