Purdue University Logo Medicinal researches rely on measurements observed in sensors, therefore, more accurate the results, better the course of treatment. In an attempt to enhance analyses for diabetes research, scientists from the Purdue University have created a technique that apparently collects artificial DNA and carbon nanotubes onto a biosensor electrode.

Presently, the sensors used do not seem to be efficient enough which leads to incorrect calculations. Of late, carbon nanotubes have emerged as an important avenue to enhance the working of sensors owing to their superior thermal and electrical traits. However, since these materials do not appear to support watery ambience, they are not utilized in biological fluids.

“In the future, we will be able to create a DNA sequence that is complementary to the carbon nanotubes and is compatible with specific biosensor enzymes for the many different compounds we want to measure. It will be a self-assembling platform for biosensors at the biomolecular level,” commented Marshall Porterfield, a professor of agricultural and biological engineering and biomedical engineering

The team formulated a synthetic DNA which can cling to the surface of the carbon nanotubes and make them more water soluble. When the nanotubes are present in the solution, the user has to place the electrode into the solution and then charge it suitably. The carbon nanotubes will envelop the surface in the process.

The sensor’s assembly is deemed to be complete as the electrode coated with carbon nanotubes tends to attract enzymes. The sensor used in this research aimed at glucose, but it may be used for other compounds too. Diabetic patients could someday use these sensors for insulin management. Porterfield believed that other sensors can also be generated using this technology.
