Scientists have developed a new technology from where a simple finger prick test may soon be possible to detect disease bio-makers in the form of nucleic acids, building blocks of all living organisms.
Nanotechnology Could Help Advance Cancer Detection, reveals Study
Nucleic acids contain sequences or chains of bases extending from just few to millions of elements long. The actual order in which these bases are found, over shortest distance, are powerfully binded to their function, and hence can be used as indicators of what is going on inside cells and tissues.
“We envision this as a potential first-line, noninvasive diagnostic to detect anything from cancer to the Ebola virus,” said lead author of the study Adam Hall, assistant professor of bio-medical engineering at Wake Forest Baptist Medical Center in North Carolina, the US.
“Although we are certainly at the early stages of the technology, eventually we could perform the test using a few drops of blood from a simple finger prick,” Hall said
Hall said “If the sequence you are looking for is there, it forms a double helix with a probe we provide and you see a clear signal. If the sequence isn’t there, then there is not any signal,”
“By simply counting the number of signals you can determine how much of the target is around,” Hall said.
However it has also confirmed that x rays, CT Scans radiations do not cause cancer.
“We envision this as a potential first-line, non-invasive diagnostic to detect anything from cancer to the Ebola virus,” said Hall. “Although we are certainly at the early stages of the technology, eventually we could perform the test using a few drops of blood from a simple finger prick,” Hall said. The findings were published in the journal Nano Letters.
So, this is about the technology which will help to in advance caner detection. If you liked this article, feel free to share it !
