Researchers control biofilm formation using optical traps

Biofilms—slimy layers formed when bacteria stick together on a surface—allow bacteria to shield themselves from extreme environments and even evade antibiotics. In a new study, researchers have shown that laser light ...

CRISPR-powered optothermal nanotweezers

Optothermal nanotweezers are an innovative optical design method that has revolutionized classical optical techniques to capture a broad range of nanoparticles. While the optothermal temperature field can be employed for ...

New fluorescent dyes help illuminate microscopic life

Inspired by the mechanism behind light-sensitive sunglasses, a team led by a North Carolina State University researcher invented a family of fluorescent dyes to illuminate biological processes at a very small scale—comparable ...

Speckle-illumination proves useful in photoacoustic microscopy

Motivated by the limitations of scanning approaches to photoacoustic microscopy, an international group supervised by Emmanuel Bossy of Université Grenoble Alpes experimented with structured illumination using known and ...

Technology development could bring Raman microscopy to the clinic

Researchers have developed a Raman microscope that can acquire information hundreds of times faster than a conventional Raman microscope. Raman microscopy is a powerful non-invasive tool for performing complex chemical analysis ...

The sound of light: Photoacoustics for biomedical applications

Medical imaging techniques provide a unique view inside the body and are invaluable for diagnosis and disease monitoring. From X-ray, over MRI to ultrasound, the field is vast and diverse. When imaging biological tissue, ...
