New ink formulation enables two-photon laser printing to fabricate dynamic, complex yet tiny structures.

How animals survive in the wild and defend themselves from natural predators is one of the most fascinating and essential mechanisms that researchers can study. Because animals cannot rely on the same mental strategies that humans can to extract themselves from dangerous situations, the animals often need to take advantage of innate physical capabilities. Photonics, in conjunction with other techniques, can help to uncover these complexities of animals’ physical structure and the functioning that enables their built-in defenses.

To unlock the mystery behind these innate safeguards, Ahmet Karabulut, a pre-doctoral researcher in the lab of Matt Gibson at the Stowers Institute for Medical Research, examined electric-looking (thanks...

Streamlined dual-wavelength excitation system can deliver accurate depth information about tissues.

Medical research has a long, unfortunate track record of excluding ethnic and racial minority groups from clinical trials, a phenomenon that introduces remarkable uncertainty to the outcomes of taking medications or receiving laser-based medical treatments in these populations. Similarly, chronic medical conditions and adverse reactions to treatment that disproportionately affect minority groups, such as people of color, have historically garnered less investigative attention than those that affect majority groups. This has led to increased morbidity and mortality in minority groups.

The U.S. Census Bureau projects that people with skin of color will constitute 50.3% of the U.S. population by 2045, up from 39.7% in 2019. As this...

A research team in Germany prototypes a fast, “assembly line”-type approach for building multiphoton entangled states—a key resource for some next-gen quantum technologies.

We are delighted to welcome Professor Jean-Christophe Baret as an Associate Editor for Lab on a Chip! Jean-Christophe Baret University of Bordeaux , France JC Baret is Professor at the University of Bordeaux and member of the Institut Universitaire de France. He obtained his PhD from the University of Twente (NL) in 2005 and joined […]

A two-photon fluorescence imaging method developed by researchers at the University of Hong Kong and the University of California, Berkeley was able to image the flow of individual blood cells at 1000 2D frames and 1,000,000 line-scans per second in the brains of awake mice.

Such rapid measurements go beyond the reach of conventional two-photon microscopy methods to enable the study of blood flow at the single-cell level in large blood vessels. The ultrafast two-photon fluorescence imaging technique could help scientists better understand how energy is distributed and regulated in both healthy and diseased brains, by revealing blood flow changes at the level of individual blood vessels and across the larger vessel network within the...

Transform microfluidics industry with your research Dolomite Microfluidic Competition 2022 is a competition for all researchers, students who are working or studying on microfluidics projects across the globe. We know scientists around the world may have many great ideas, but don’t have enough resources for their projects. Therefore, Dolomite Microfluidics would like to organize this competition […]

As scientists seek to image deeper in tissue with high enough resolution to track cellular processes, they are increasingly turning to multiphoton techniques. In multiphoton microscopy, longer-wavelength photons, which have lower energy and penetrate further than their shorter-wavelength counterparts, cause less tissue damage while imaging at greater depths. But, historically, these systems have required sophisticated and complex instrumentation that has put them out of reach for many clinical and laboratory settings.

This situation is changing. In our January/February issue, we published a story by Mihaela Balu, who wrote about a compact imaging head that could house a femtosecond fiber laser along with associated optics and...

Endangered animals, quite understandably, do their best not to be found. So it took the aid of sophisticated imaging and recording technology for a team of researchers from Finland and the U.K. to capture the habits and movements of tree hyraxes in the mountains of Kenya.

Tree hyraxes, mainly found in Africa, are nocturnal mammals with a guinea pig-like appearance that, as their name suggests, spend a lot of time in trees.

Takeaways from the researchers’ study included: the higher in trees the better for an individual animal’s survival, and the bigger the forested areas the better for providing food...
