New Nanowires Findings from Zhejiang University Described

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Nanowires have been published. According to news originating from Hangzhou, People's Republic of China, by NewsRx correspondents, research stated, "A nanoprobe based on a single nanowire (NW) possesses substantial potential for biological and in vivo determination. With regard to intracellular detection, minimal invasion and an adjustable detection depth have become crucial challenges."

Our news journalists obtained a quote from the research from Zhejiang University, "Nanoprobes with small, sharp tips, and long arms are thus desired. Here, we demonstrate a general strategy to prepare a single kinked NW heterojunction with a continuously adjustable angle, length and sharp line-type tip. It is found that heterojunction barriers introduced into kinked NWs can be used as a functional factor to interact with biomolecules and cells. The prepared kinked NW nanosensor is successfully used for the highly-sensitive probe-free detection of hemoglobin and real-time intracellular recording with minimal invasion. The sensing performance is dependent on the amount of heterojunction barriers. Integrated nanoprobes with multi-shaped structures are further designed for multi-functional applications."

According to the news editors, the research concluded: "Introducing heterojunction barriers to kinked NWs provides a substantial opportunity for fabricating functional and integrated nanoprobes for applications in the life sciences."
