Nanoelectronic Biosensors

Nanotechnology experts and engineers are capable of creating nanodevices that incorporate the use of conductive materials as electronic sensors. The sensors are able to recognize biological changes and patters at the nanoscale level, and identify them as indicators of an oncoming medical condition. Nanomedicine experts are excited about the emergence of this technology, and plan to use it as a way of developing unique nano-electronic biosensors to be used in the long-term prevention and discovery of disease. These sensors would be capable of detecting heart attacks before they happened, or the development of tumor cells in the early stages, leading to a faster reaction by doctors and more preemptive medical treatments. Early recognition is one of the most effective ways of treating some of the most deadly diseases, including cancer, and researchers believe that nanotechnology and biomedical engineering could make a difference in the long term prevention of these diseases.

Biomedical sensors incorporate designated nanoparticles with the ability to detect changes in the body’s makeup. The nanoparticles recognize specific tell signs of the development of different medical conditions. For example, noticing changing structures in the cells or high levels of a chemical substance. Another method of nanoparticle bio-sensing revolves around using nanoparticles equipped with anti-bodies or structures of DNA to be able to scope out and locate instances of genetic material indicative of an oncoming medical condition. The DNA allows the nanoparticle to recognize and seek out the substance, and relay a signal back to the patient or doctor. The nanoparticle is attached the DNA or anti-body using either the attractive properties of magnetic nanoparticles or a special adhesive coating.

The advantage of nanosensors is that they can be administered by doctors to at risk patients and relay signals about the status of the patient’s health directly to the doctor. Nanosensors rely on the conductive properties of the materials used in the nanoparticles and their combination to send electrical signals between the sensor and a remote device that measures the readings. To ensure the transferal of information and the effectiveness of the conductivity many nanosensors are made using nanowires, thin strands of nanomaterials that are highly conductive. With the accurate readings of the nanosensors, doctors are able to identify the location of diseases and malign cell growths and issue treatment.
