Cheap, Ultra-Sensitive Colour Test Spots Early HIV, Cancer

Researchers in the UK have developed a "naked eye" colour test for virus and disease biomarkers that is ten times more sensitive than current gold standard methods. They have tested it on HIV and prostate cancer biomarkers, and suggest it offers a cheap and simple way of spotting early onset of these and other diseases that could be of particular benefit in poorer countries.

In a paper published online in Nature Nanotechnology on 28 October, Roberto de la Rica and Molly Stevens, from Imperial College London, write how their prototype visual sensor technology detected an HIV biomarker called p24 in blood samples.

"Our approach affords for improved sensitivity, does not require sophisticated instrumentation and it is ten times cheaper, which could allow more tests to be performed for better screening of many diseases," she adds.
 
 

Prostate Cancer, Other Diseases

De la Rica and Stevens also report how they tested their method's ability to detect low levels of Prostate Specific Antigen (PSA), which can be an early indicator for prostate cancer.

They say the test can be reconfigured to detect known biomarkers of other viruses and diseases.

"We have developed a test that we hope will enable previously undetectable HIV infections and indicators of cancer to be picked up, which would mean people could be treated sooner," says de la Rica, from the Department of Materials at Imperial.

The school started out with 61 students, one associate professor and seven tutors. In 1956, when the school of Arts opened, the two schools merged to form the University of Mashhad. In 1989, the faculties offering Medical Sciences' degrees across the country separated from the Ministry of Culture and Higher Education. New emerging Medical Universities have gone under management of Ministry of Health, Treatment and Medical Education. Thus the original University of Mashhad was divided into two independent universities: "Ferdowsi University of Mashhad" and "Mashhad University of Medical Sciences'. Mashhad University of Medical Sciences operates at present with 8 faculties, 32 hospitals, 179 rural and 147 urban health centers. It covers an enormous area stretching from the north east to the central parts of the country, which makes it the largest university of Medical Sciences providing health care and treatment services. With 597 teaching staff, 1645 MDs with different specialties, 138 dentists, 123 pharmacists and 25, 402 employees, the university provides health care and medical services to the area's large population as well as to over 25 million tourists a year.
