A study published in ACS Nano presents a novel biosensor for the isothermal, highly sensitive detection of bladder cancer biomarkers—miRNAs, short non-coding RNAs that regulate gene expression—using programmable pH-responsive ...
As scientists have probed the mysteries of life down to smaller and smaller scales, they have invented tools to help them understand what they observe. Determining the identity of DNA and RNA molecules has now become commonplace ...
Only in cancer medicine do clinicians aim to attack and kill legions of a patient's own cells. But healthy bystander cells often get caught in deadly crossfire, which is why cancer treatments can cause severe side effects ...
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 ...
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 ...
From the tension of contracting muscle fibers to hydrodynamic stresses within flowing blood, molecules within our bodies are subject to a wide variety of mechanical forces that directly influence their form and function. ...
New research may revolutionize the slow, cumbersome and expensive process of detecting the antibodies that can help with the diagnosis of infectious and auto-immune diseases such as rheumatoid arthritis and HIV. An international ...
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 ...
A complex interplay of molecular components governs almost all aspects of biological sciences - healthy organism development, disease progression, and drug efficacy are all dependent on the way life's molecules interact in ...
(Â鶹ÒùÔº)—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 ...
