The diffraction limit is a fundamental barrier in optical microscopy, restricting the smallest resolvable feature size of microscopic imaging system. Microsphere-assisted super-resolution microscopy has emerged as promising approach for overcoming this limit. This technique offers several advantages, including no need fluorescent dyes, easy operation under white light illumination, and good compatibility with commercial microscopes. Various strategies have been proposed to enhance performance microspheres. Recently, patchy microspheres were found exhibit capabilities air an enhanced contrast. In work, we studied fully immersed liquid. Furthermore, demonstrated formation photonic hooks from within liquid environment. findings study will extent application immersion mode, opening up new possibilities environment

Monitoring of microvascular calcification (MC) is essential for the understanding pathophysiological processes and characterization certain physiological states such as drug abuse, metabolic abnormality, chronic nephrosis. In this work, we develop a novel effective time-resolved photoacoustic microscopy (TR-PAM) technology, which can observe obvious bio-elastic change in development process MC owing to calcium deposition along vascular walls.The feasibility TR-PAM imaging was validated using group agar phantoms

To correct the refraction aberration induced by skull in photoacoustic imaging, a method for phase distortion compensation is proposed based on angular spectrum theory with aid of ultrasonic signals. This first updates speed sound distribution iteratively performing correction reconstruction. Then obtained ultrasound-assisted serves as prior knowledge to address adjusting shift factor wavefront different media. Finally, aberration-corrected ultrasonic-photoacoustic dual-modality image can be obtained. Numerical simulations and phantom experiments confirm effectiveness this method. Specifically, simulations, position error reduced from -13.61 % 1.27 depth compared reconstruction constant speed. Moreover, real ex-vivo rabbit experiment illustrates potential biological application transcranial imaging.
