Nano DNA thermometer created

Scientists have made a programmable DNA thermometer that is 20,000 times smaller than a human hair. The invention was reported in the journal Nano Letters. The new device may significantly aid our understanding of natural and human designed nanotechnologies by enabling to measure temperature at the nanoscale. The device was created by researchers at the University of Montreal in Canada.
Say the researchers, In recent years, biochemists also discovered that biomolecules such as proteins or RNA (a molecule similar to DNA) are employed as nanothermometres in living organisms and report temperature variation by folding or unfolding. Inspired by those natural nano thermometers, which are typically 20,000x smaller than a human hair, we have created various DNA structures that can fold and unfold at specifically defined temperatures. There are still many unanswered questions in biology. For example, we know that the temperature inside the human body is maintained at 37 degree Celsius, but we have no idea whether there is a large temperature variation at the nanoscale inside each individual cell.
