A new nanoscience-based diagnostic method called bio-bar-code amplification (BCA) has been developed, rivaling PCR in sensitivity and selectivity. BCA can detect as few as 10 DNA molecules in a sample in minutes, making it suitable for point-of-care diagnostics at various locations.
Researchers developed a new method to increase fetal DNA detection in maternal blood, reducing the risk of pregnancy loss associated with invasive tests. The technique, using formaldehyde to stabilize blood cell membranes, resulted in higher percentages of free fetal DNA in samples.
Researchers at UCSB have created an electronic detector for DNA that can identify specific types of genetic material without the need for reagents or lengthy processing times. This breakthrough aims to simplify diagnostic tests for diseases such as strep throat, potentially leading to faster and more accurate diagnoses.
Researchers at the University of Rochester have developed a new DNA chip that can rapidly detect and identify dangerous pathogens. The chip uses a simple method to analyze genetic material quickly and accurately, eliminating time-consuming steps typically used in traditional techniques.
Researchers at the University of Toronto have developed a novel nanoscale electronics circuit that can detect the presence of a single electron. This breakthrough could enable the creation of ultra-sensitive biosensors capable of detecting important biological molecules, including DNA.
Northwestern University scientists developed a new DNA detection method that excels in sensitivity, selectivity, cost, ease of use, and speed. The technology can detect hundreds of pathogenic agents simultaneously and pinpoint single-base mismatches missed by conventional methods.
Nanosphere has developed ultra-sensitive and specific DNA detection technology using electrical conductivity measurements facilitated by gold nanoparticle probes. This breakthrough can simplify traditional analysis procedures, reducing costs and increasing the speed of hand-held molecular testing devices.
