Structured illumination microscopy (SIM) is the most preferable system for live-cell super-resolution imaging. It enables the observation of intricate subcellular dynamics. However, conventional SIM ...

An acoustic “tractor beam” that can pull an object by firing sound waves at it has been created by physicists in the UK and US. The beam was made using a commercial ultrasound surgery system and ...

In International Journal of Extreme Manufacturing, a new laser machining method that dynamically adapts its beam shape is proposed to fabricate microgrooves with ...

The tractor beam was able to move a hollow triangular object forward 1cm This was done with a device that exerted pressure using sound waves Device could have applications in treating cancer and ...

Peking University, Aug 18, 2025: Professor Xi Peng’s team from the College of Future Technology at Peking University has recently developed a triangle structured illumination microscopy (SIM), which ...

While beam-shaping strategies have allowed researchers to sculpt the cross-sectional shape of laser spots—using, for example, triangular beams to carve triangular channels—the interaction of such ...
