Gaming system a new step for telepathology and other telemedicine fields Online crowd-sourcing – in which a task is presented to the public, who respond, for free, with various solutions and suggestions – has been used to evaluate potential consumer products, develop software algorithms and solve vexing research-and-development challenges. But diagnosing infectious diseases? Working on the assumption that large groups of public non-experts can be trained to recognize...

In the fight against emerging public health threats, early diagnosis of infectious diseases is crucial. And in poor and remote areas of the globe where conventional medical tools like microscopes and cytometers are unavailable, rapid diagnostic tests, or RDTs, are helping to make disease screening quicker and simpler. RDTs are generally small strips on which blood or fluid samples are placed. Specific changes in the color of the strip, which usually occur within minutes, indicate the...

Device described in Biomedical Optics Express could be used for field diagnostics in developing countries, testing of water quality, food contamination To serve remote areas of the world, doctors, nurses and field workers need equipment that is portable, versatile, and relatively inexpensive. Now researchers at the University of California at Los Angeles (UCLA) have built a compact, light-weight, dual-mode microscope that uses holograms instead of lenses. The team describes the new device...

Flow cytometry, a technique for counting and examining cells, bacteria and other microscopic particles, is used routinely in diagnosing disorders, infections and cancers and evaluating the progression of HIV and AIDS. But flow cytometers are big, bulky contraptions that cost tens of thousands of dollars, making them less than ideal for health care in the field or other settings where resources are limited. Now imagine you could achieve the same results using a device that weighs about half an...

UCLA researchers have redefined the concept of a microscope by removing the lens to create a system that is small enough to fit in the palm of a hand but powerful enough to create three-dimensional tomographic images of miniscule samples. The advance, featured this week in the early online edition of the journal Proceedings of the National Academy of Sciences, represents the first demonstration of lens-free optical tomographic imaging on a chip, a technique capable of producing...

Microfluidic device uses antibodies to 'capture' white blood cells called T cells affected by HIV UC Davis biomedical engineer Prof. Alexander Revzin has developed a "lab on a chip" device for HIV testing. Revzin's microfluidic device uses antibodies to "capture" white blood cells called T cells that are affected by HIV. In addition to physically binding these cells the test detects the types and levels of inflammatory proteins (cytokines) released by the cells. Revzin's team collaborated...

Lensless cellphone microscope receives 3 major awards Cell phones are accumulating a Swiss Army Knife-esqe assortment of capabilities; substituting as cameras, providing internet access, and soon operating as medical labs if Aydogan Ozcan's plans come to fruition. This month's cover article of the journal Lab on a Chip features the latest creation by the Ozcan group, a functioning prototype of a cell phone microscope. The lensless imaging platform behind the cell phone microscope is nearing...

New advances result in accurate ID of smaller particles using holograms Cell phones have already revolutionized the way people around the world communicate and do business. Thanks to advances being made at UCLA, they are about to do the same thing for medicine. In the lab of UCLA electrical engineering professor Aydogan Ozcan, a prototype cell phone has been constructed that is capable of monitoring the condition of HIV and malaria patients, as well as testing water quality in undeveloped...
