To improve health monitoring, simply trip the 'nanoswitch'

Engineered strands of DNA—nanoscale tools called "nanoswitches"—could be the key to faster, easier, cheaper and more sensitive tests that can enable high-fidelity detection of biomarkers indicating the presence of different ...

Cellular microRNA detection with miRacles

MicroRNAs (miRNAs) are short noncoding regulatory RNAs that can repress gene expression post-transcriptionally and are therefore increasingly used as biomarkers of disease. Detecting miRNAs can be arduous and expensive as ...

New nanodevice defeats drug resistance

Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking the gene that ...

Bioengineers design rapid, easy-to-use diagnostic tests

(Phys.org)—By mimicking nature's own sensing mechanisms, bioengineers at UC Santa Barbara and University of Rome Tor Vergata have designed inexpensive medical diagnostic tests that take only a few minutes to perform. Their ...
