New, old science combine to make faster medical test

23-Jan-2017 - A UCF researcher has combined cutting-edge nanoscience with a magnetic phenomenon discovered more than 170 years ago to create a method for speedy medical tests. The discovery, if commercialized, could lead to faster test results for HIV, Lyme disease, syphilis, rotavirus and other infectious ...

Combatting antimicrobial resistance with smartphones

A simple and inexpensive attachment could help to expand testing to regions with limited resources.

16-Dec-2016 - A team of UCLA researchers has developed an automated diagnostic test reader for antimicrobial resistance using a smartphone.

Microneedle patch could replace standard tuberculosis skin test

28-Aug-2013 - Each year, millions of people in the United States get a tuberculosis skin test to see if they have the infection that still affects one-third of the world’s population. But the standard diagnostic test is difficult to give, because a hypodermic needle must be inserted at a precise angle and ...

Large-scale genomic analysis of prostate cancer unveiled

28-Jun-2010 - A unique collaboration among physician-scientists at Memorial Sloan-Kettering Cancer Center (MSKCC) has yielded the most comprehensive genomic analysis of prostate cancer to date.
