Hologram technology developed at UCLA could lead to improved diagnoses of chronic diseases in remote areas

12 August, 2017 Maxim Batalin

A new system developed by UCLA researchers could make it easier and less expensive to diagnose chronic diseases, particularly in remote areas without expensive lab equipment. The technology uses extremely simple optical hardware and a lens-free microscope, as well as sophisticated algorithm...

Glowing Tumor Technology Helps Surgeons Remove Hidden Cancer Cells

10 August, 2017 Biophotonics.World

Surgeons were able to identify and remove a greater number of cancerous nodules from lung cancer patients when combining intraoperative molecular imaging (IMI) – through the use of a contrast agent that makes tumor cells glow during surgery – with preoperative positron emission tomography (PET) scan...

Researchers set record for fastest light pulse

14 August, 2017 Biophotonics.World

A research team at the University of Central Florida has demonstrated the fastest light pulse ever developed, a 53-attosecond X-ray flash. The group led by Professor Zenghu Chang beat its own record set in 2012: a 67-attosecond extreme ultraviolet light pulse that was the fastest at the time. At one...

Nanoscale tracking of invasomes in the stratum corneum

08 August, 2017 Volker Deckert

When administering drugs, the human body has several barriers, a drug has to pass to reach the preferred site of action. For percutaneous application, this barrier is stratum corneum. Frequently, liposomal formulations are used to increase the drug’s penetration through the skin. Up to now, the exac...

Investigators use light to kill microbial 'vampires'

07 August, 2017 Biophotonics.World

On July 24 Vanderbilt scientist Eric Skaar, Ph.D., MPH, summarized his group's latest paper in a tweet: "If S. aureus is going to drink our blood like a vampire, let's kill it with sunlight.""That thing has been retweeted so many times," said Skaar, the Ernest W. Goodpasture Professor of Pathology i...

Building bridges within the cell -- using light

03 August, 2017 Biophotonics.World

Each cell in the body is made up of a number of tiny sealed membranous subunits called organelles, and they send things like lipids back and forth to allow the cell to function. A process called membrane tethering is responsible for bridging the gap between organelles at a specialized subcellular zo...

Shedding light deeper into the human brain

02 August, 2017 Biophotonics.World

The inner workings of the human brain have always been a subject of great interest. Unfortunately, it is fairly difficult to view brain structures or intricate tissues due to the fact that the skull is not transparent by design. The reality is that light scattering is the major obstacle for deep pen...
