Transparent ultrasound chip improves cell stimulation and imaging

Ultrasound scans, best known for monitoring pregnancies or imaging organs, can also be used to stimulate cells and direct cell function. A team of Penn State researchers has developed an easier, more effective way to harness ...

Novel assay finds new mechanism underlying red blood cell aging

Red blood cells are the most abundant cell type in blood, carrying oxygen throughout the human body. In blood circulation, they repetitively encounter various levels of oxygen tension. Hypoxia, a low oxygen tension condition, ...

Deep learning and holography create a better point-of-care sensor

Agglutination assays are widely used immunological sensors based on antigen-antibody interactions that result in clumping of antibody-coated microscopic particles. Once the sample—for example, a patient's serum—is introduced, ...

Efficiently smuggling drugs into cells

A new, patented method called Progressive Mechanoporation makes it possible to mechanically disrupt the membranes of cells for a short time period and let drugs or genes inside cells. In this way, researchers can test new ...
