Nut clusters. Cupcakes. Just thinking of these makes you want to run for the cupboard to see what kind of delicious treats you have in there, doesn’t it? As delicious as these sound, this week’s show focuses on a different form of each.
This week on One Cell One Light Radio, Dr. Hildy welcomes returning guest Dr. Zhong Lin (ZL) Wang, head of a leading group in nanoscience and nanotechnology at the Georgia Institute of Technology, to discuss the concepts of Nanoscale Triboelectric-Effect-Enabled Energy Conversion for Sustainably Powering Portable Electronics, about which Dr. Wang’s paper states:
“ Harvesting energy from our living environment is an effective approach for sustainable, maintenance-free, and green power source for wireless, portable, or implanted electronics.” AND his new Arrays of transistors made of nanowires which could form the basis of a new class of devices nearly as sensitive to mechanical force as human skin is, according to research published recently in Science.
Further discussion will include “nano cupcakes”, “nano nut clusters” for X-Ray Vision, cleaning the air with blue jeans and medical records chips inserted into the arm. (SEE LINKS for in-depth information.)
For a while carbon nanotubes have been a hot topic in science. Some of the latest research on nanotubes done at the US National Institute of Standards and Technology in Boulder, CO are fondly called “cupcakes.”
If scientists are going to use terahertz radiation, a highly powerful form that can act as x-ray “vision”, they need to be able to measure it and are working on ways to measure properties of terahertz lasers emitting this radiation. They decided to use nanotubes as a coating on a detector to try to enhance the detector’s ability to measure the energy radiated on it by a terahertz laser. The best detector would be able to absorb all the energy radiated on it and transform it to something measurable, like an electric current.
At NIST, they decided to try carbon nanotubes. They grew vertically aligned, multi-walled, carbon nanotubes of different lengths onto a silicon substrate. These “cupcakes” absorbed almost all the terahertz radiation from a laser. It turns out that the longer the nanotubes were in the cupcake, the more laser light (radiation) it absorbed.
Scientists have also developed nanometer-sized ‘cargo ships’ that can sail throughout the body via the bloodstream without immediate detection from the body’s immune radar system and ferry their cargo of anti-cancer drugs and markers into tumors that might otherwise go untreated or undetected. These microscopic cargo ships could one day provide the means to more effectively deliver toxic anti-cancer drugs to tumors in high concentrations without negatively impacting other parts of the body.
The nanometer-sized cargo ships look individually like a chocolate-covered nut cluster, in which a biocompatible lipid forms the chocolate shell and magnetic nanoparticles, quantum dots and the drug doxorubicin are the nuts.
A far cry from nougat, caramel and pecans, indeed.
Join Dr. Hildy and her guest this week as they discuss new advances in nanotechnology and, among other things, their comparison to delicious treats, on One Cell One Light Radio!

Zinc Oxide Nanowires Transistors Can Be Sophisticated Pressure Sensors | MIT Technology Review
Arrays of transistors made of nanowires could form the basis of a new class of devices nearly as sensitive to mechanical force as human skin is, according to research published today in Science.
The inventor of the technology, Zhong Lin Wang, a professor of materials science and engineering at Georgia Tech, says it has immediate applications in human-machine interfaces. For example, it could be used to capture electronic signatures by recording the distinctive force an individual applies while signing. Down the road, says Wang, his group’s pressure sensor arrays could equip robotics and prosthetics with a human-like sense of touch. >>>
