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 ...
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 ...
