We present a new approach for shaping light at the output of a multimode fiber by
modulating the transmission matrix of the system rather than the incident light. We apply …

Background Photoactivation targeting macrophages has emerged as a therapeutic strategy
for atherosclerosis, but limited targetable ability of photosensitizers to the lesions hinders its …
