Diseases, like cancer, usually develop over years before symptoms appear. This is because the altered biomarkers are generally present in low numbers, and are extremely difficult to detect, posing a needle-in-a-haystack problem.
Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. The Advanced Cytometry Labs at Macquarie has invented and demonstrated a library of hypersensitive molecular probes – SUPER Dots – able to pinpoint small numbers of abnormal cells in water, blood and urine.
It improves the detectable limits by orders of magnitude, promising non-invasive early-stage diagnosis.
