Optical-Memory Transport Imaging: A Transport-History Framework for Finite-Memory Tracers
Haichun Liu, Jerker Widengren
Finite-memory optical tracers encode upstream transport histories rather than instantaneous local flow velocities. We introduce optical-memory transport (OMT) imaging, a framework…

Lanthanide upconversion nonlinearity: a key probe feature for background-free deep-tissue imaging
Niusha Bagheri, Chenyi Wang, Du Guo +7
Lanthanide-based upconversion nanoparticles (UCNPs) have attracted considerable attention in biomedical applications, largely due to their anti-Stokes shifted emission enabling aut…
