Trace quantities of tumour biomarkers can be detected in unprocessed blood samples using nanoparticle technology developed at the University of New South Wales. The electrochemistry-based approach ...

Nucleic acids may be labeled at their 3’ end, 5’ end, or throughout the molecule, depending on the desired application. Myriad of enzymatic or chemical methods are utilized to generate nucleic acids ...

A few years back, the 50th anniversary of the discovery of the structure of the DNA double helix by biologists James D. Watson and Francis H. C. Crick was grandly celebrated. In fact, it's a double ...

In the case of nucleic acid tests, polymerase chain reaction (PCR) has been the gold standard for single-molecule diagnosis. Single-molecule detection of pathogens, such as severe acute respiratory ...

DNA is the poster child for high-specificity binding. As long as their base sequences match, two complementary strands of DNA can navigate through a sea of biomolecules, find each other, and hold fast ...
