Microneedle patch encourages hair to regrow
Credit: ACS Nano A scanning electromicrograph of the microneedle patch. Each needle is 300 μm in diameter at its base and 600 μm tall. Mice treated with the drug-delivery device regrew hair in less than 1 week by Bethany Halford APRIL 12, 2019 | APPEARED...
For faster and cheaper diagnosis, UCLA engineers are using deep learning to digitally stain tissue
To help identify diseases, pathologists typically manually apply colored dyes, or stains, to label tissue samples. The stains help highlight microscopic structures and provide a visible color contrast between healthy tissue and anomalies. But the process is...
New class of membranes shown to regenerate tissue and bone, viable solution for periodontitis
Alireza Moshaverinia, left, and Paul Weiss are co-lead authors of the study. Periodontitis affects nearly half of Americans ages 30 and older, and in its advanced stages, it could lead to early tooth loss or worse. Recent studies have shown that periodontitis could...
Mobile-phone microscope detects the “silent killer” of honey bees
Demonstration of the use of the portable smartphone-based parasite sensor. BIOLOGY Bees are among the most important species responsible for pollinating about one-third of the world’s food supply, with their contribution in the United States alone valued at $15-20...
Artificial intelligence detects the presence of viruses
Deep learning-based sensing of viruses using holography. Credit: UCLA Engineering Institute for Technology Advancement Many biosensing applications rely on characterization of specific analytes such as proteins, viruses and bacteria, among many other targets, which...
Deep learning takes fluorescence microscopy into super resolution
UCLA-led team produces images on a laptop that match the quality of those from high-end equipment Wayne Lewis | December 17, 2018 The technique transforms low-resolution images from a fluorescence microscope (a) into super-resolution images (b) that compare favorably...
Artificial intelligence-based device detects moving parasites in bodily fluid for easier, earlier diagnosis
Developed by UCLA Engineering researchers, system is ‘like a motion detector for the microscopic world Amy Akmal | December 14, 2018 The device developed at UCLA Engineering can analyze more than 3 milliliters of fluid in 20 minutes, much faster than traditional...
Sprayable gel developed by UCLA-led team could help the body fight off cancer after surgery
A scanning electron microscope image of a gel developed by UCLA researchers that could help prevent cancer from recurring after surgery. Many people who are diagnosed with cancer will undergo some type of surgery to treat their disease — almost 95 percent of people...
Two-cells-in-one combo could be platform to bolster leukemia treatment
Led by UCLA bioengineer, researchers design delivery system to guide drugs directly to cancer cells ‘hiding’ in bone marrow Matthew Chin | October 29, 2018 Zhen Gu Research Lab/UCLAA scanning electron microscope colorized to show the hematopoietic stem cells (purple)...
