Researchers used a two-photon phosphorescent probe to monitor capillary flux and oxygen in sets of capillaries, obtaining a robust oxygen and flux estimate within each capillary, sufficient to observe ...

Increasing the levels of a particular phospholipid in the membranes of brain cells may offer a promising new way to improve blood circulation in the brain and support healthier brain activity. A poten ...

Researchers at Johns Hopkins Medicine say they have used a "zap-and-freeze" technology to watch hard-to-see brain cell communications in living brain tissue from mice and humans. Findings from the new ...

Figure 1. Conceptual illustration of label-free, multiphoton photoacoustic microscope (LF-MP-PAM). Near-infrared femtosecond laser enable us to observe endogenous NAD(P)H of neurons in brain slice and ...
