Researchers from Indian Institute of Science Report Findings in Titania Nanotubes (Titania nanotube-modified screen printed carbon electrodes enhance the sensitivity in the electrochemical detection of proteins)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Titania Nanotubes have been published. According to news originating from Bangalore, India, by NewsRx correspondents, research stated, "The use of titania nanotubes (TiO2-NT) as the working electrode provides a substantial improvement in the electrochemical detection of proteins. A biosensor designed using this strategy provided a robust method to detect protein samples at very low concentrations (C-protein ca 1 ng/mu l)."

Our news journalists obtained a quote from the research from the Indian Institute of Science, "Reproducible measurements on protein samples at this concentration (I-p,I-a of 80 +/- 1.2 mu A) could be achieved using a sample volume of ca 30 mu l. We demonstrate the feasibility of this strategy for the accurate detection of penicillin binding protein, PBP2a, a marker for methicillin resistant Staphylococcus aureus (MRSA). The selectivity and efficiency of this sensor were also validated using other diverse protein preparations such as a recombinant protein tyrosine phosphatase (PTP10D) and bovine serum albumin (BSA). This electrochemical method also presents a substantial improvement in the time taken (few minutes) when compared to conventional enzyme-linked immunosorbent assay (ELISA) protocols."

According to the news editors, the research concluded: "It is envisaged that this sensor could substantially aid in the rapid diagnosis of bacterial infections in resource strapped environments."
