Ovarian cancer is usually diagnosed only after it has reached an advanced stage, with many tumors spread throughout the abdomen. Most patients undergo surgery to remove as many of these tumors as possible, but because some are so small and...

Researchers at the California Institute of Technology (Caltech) Optical Imaging Laboratory (Pasadena, CA) have developed a technique for in vivo superresolution photoacoustic computed tomography (PACT) that breaks the acoustic diffraction limit by localizing the centers of single dyed droplets flowing...

Lensless microscopy with X-rays, or coherent diffractive imaging, is a promising approach. It allows researchers to analyse complex three-dimensional structures, which frequently exist in nature, from a dynamic perspective. Whilst two-dimensional images can already be generated quickly and in an...

Biotechnologists, physicists, and medical researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed technology for microscopic imaging in living organisms. A miniaturised multi-photon microscope, which could be used in an endoscope in future, excites the body’s own molecules to illuminate and enables...

Scientists at the U.S. Naval Research Laboratory (NRL) discovered a new method to passivate defects in next generation optical materials to improve optical quality and enable the miniaturization of light emitting diodes and other optical elements. “From a chemistry standpoint,...

Engineers at the University of Wisconsin-Madison have developed a compact, single-shot, free-space-coupled spectrometer with hyperspectral imaging capabilities that can be integrated with a cellphone. The spectrometer is fabricated on top of and integrated with a CMOS chip. The miniaturized device...

Researchers in Switzerland and Australia have brought together the physics of dielectric metasurfaces and hyperspectral imaging to create an ultrasensitive, label-free biosensing platform (Nat. Photon., doi: 10.1038/s41566-019-0394-6). The team believes that the platform—reportedly capable of detecting and analyzing samples at...

For autonomous vehicles, lidar is an essential technology to recognize and detect surrounding objects. Researchers at KTH have taken aim at the key component of lidar, optical beam-stearing, and developed a device that is significantly cheaper to manufacture, lighter and...

Thanks to a microscopy method, a team of researchers at the Pasteur Institute (Paris, France) and the French National Institute of Health and Medical Research (INSERM; also in Paris) has revealed that chimeric antigen receptor (CAR) T cells can induce...

A novel composition of germanosilicate glass, created by adding zinc oxide, has properties that could be valuable for lens applications. The new family of zinc germanosilicate glass was invented by a research group at The Pennsylvania State University (Penn State)....
