Earlier this year the US National Nanotechnology Initiative (NNI) through its National Nanotechnology Coordination Office (NNCO) established a student contest for nano images, EnvisioNano, (it’s mentioned in my April 9, 2015 post) and, now, a May 6, 2015 news item on Nanowerk announces the winner,
The National Nanotechnology Coordination Office (NNCO) has announced the winner of the first EnvisioNano nanotechnology image contest for students. Kyle Nowlin from the University of North Carolina Greensboro Joint School of Nanoscience and Nanoengineering won the top honors for his image entitled Polymer Nanocone Array.
The image, shown below, explores new ways of controlling the spread of bacteria and fungi through the use of nanostructured surfaces (NSS). Many insects have NSS that kill microbes on the outermost layer of their exoskeletons, protecting them from infection. Kyle’s research concentrates on creating new synthetic NSS materials in the lab that resemble those found in nature. Congratulations to Kyle!
Here’s the image,
A May ?, 2015 NNCO news release, which originated the news item, offers Kyle Nowlin’s description of his winning image,Kyle’s description of his research: “Many insects display nanostructured surfaces (NSS) on their cuticles and many of these native NSS are inherently antimicrobial and kill microbes by mechanical/structure means. Our research explores the mechanisms that underlie the rupture of microbes on NSS. The native insect cuticles are complex materials that are difficult to replicate and to control specific surface properties. We have applied a colloidal lithographic process to generate novel synthetic NSS materials that resemble their biological insect cuticle counterparts in scale and shape but by using different polymeric materials to make these NSS can control surface properties of our biomimetic NSS. In this manner we will systematically identify the mechanical and physiochemical properties of rupturing NSS that lead to microbial demise. The goal of this research is to develop novel means of controlling the spread of pathogenic bacteria and fungi through nanostructured materials.”
The NNCO news release also provides more details about this year’s (2015) contest (Note: A link has been removed),
Thirty-two images were submitted by 10 students from universities across the country. Images were posted online for public voting. The top five images advanced to the semifinalist round. The final winner was chosen by representatives of the National Nanotechnology Initiative member agencies.
Congratulations to Kyle Nowlin!
