Laser Photoacoustic Microscopy
The Review of Laser Engineering, 1983 We have performed photoacoustic micro-imaging using a microphone detection technique. A microcomputer controlled photoacoustic imaging system is developed. A sample on a sensitive photoacoustic cell is scanned mechanically and photoacoustic signals generated by a focused laser beam are detected with a condenser microphone and a lock-in amplifier.

Programmable three‐state nanoreactor for spatiotemporally controlled tumor therapy
BMEMat, EarlyView.The OMVs are shielded with a biocompatible Da–Ca shell, which prolongs its circulation period and promotes intratumoral accumulation. Importantly, the biocompatible Da–Ca shell can be controllably disintegrated in tumor microenvironment by using laser irradiation, generating in situ hyperthermia and releasing Ca2+.
