Nanoscale power plants
Abstract:
For the over 100 million people worldwide who suffer from diabetes, testing blood glucose is the only way to be sure that it is within normal range and allows them to adjust the insulin dose if it is not. The current method for monitoring blood glucose requires poking your finger to obtain a blood sample. The equipment needed to perform the blood test includes a needle device for drawing blood, a blood glucose meter, single-use test strips, and a log book. Now imagine this scenario: your doctor implants a tiny device the size of a rice grain under your skin. This device automatically and accurately measures your blood glucose levels at whatever intervals, even constantly if required. It transmits the data to an external transceiver. If any abnormality is detected, the device warns you and automatically transmits the data to your doctor's computer. This scenario is one of the many promises of nanomedicine where in-situ, real-time and implantable biosensing, biomedical monitoring and biodetection will become an everyday fact of normal healthcare. Nanosensors are already under intense development in laboratories around the world. One of the important components for implantable nanosensors is an independent power source, either a nanobattery or a nanogenerator that harvests energy from its environment, so that the sensor can operate autonomously. Not only has such a nanogenerator now been developed, but a new prototype has been demonstrated to effectively generate electricity inside biofluid, e.g. blood. This is an important step towards self-powered nanosystems.
