The NISE Net is a national community of researchers and informal science educators dedicated to fostering public awareness, engagement, and understanding of nanoscale science, engineering, and technology.
Red blood cells carry a protein called hemoglobin which has a molecular structure adapted to transport oxygen to body tissues. This scanning electron micrograph shows the cells' characteristic donut-like shapes.
Nanotubes Mimicking Gecko Feet
The nanoscale structures on a gecko's foot enable it to cling to most surfaces. This scanning electron microscope image shows multiwalled carbon nanotubes attached to a polymer backing, an experiment designed to replicate the gecko foot's adhesive properties.
The gecko's amazing ability to cling to vertical or inverted surfaces is due to the interaction between nanoscale structures on its feet and tiny crevices on the wall or ceiling. The soles of gecko feet are made up of overlapping adhesive lamellae covered with millions of superfine hairs, or setae, each of which branches out at the end into hundreds of spatula-shaped structures. These flexible pads—each measuring only a few nanometers across—curve to fit inside unseen cracks and divots on the surface. The combined adhesion of these millions of pads holds the gecko in place.
Gold Nanoshells (optical microscope)
To create this optical microscope image, gold nanoshells were dispersed in a drop of water which then dried on a glass microscope slide. The colors are due to selective scattering of light by nanoscale particles.
Gold Nanoshells have a variety of uses in nanotechnology, and especially in biomedical applications. Nanoshells like these may play important roles in new kinds of cancer treatments, disease detection, and imaging techniques.
Science rapper Mike Wilson AKA Coma Niddy has created several different nanotechnology videos.
Did you know that silver has antimicrobial abilities? The same silver that is in jewelry can kill germs, fungus and bacteria. Some scientists have developed nano-silver which is even more effective at blasting away germs. Learn all about here at Coma Niddy University!
Quarked! - Adventures in the Subatomic Universe brings subatomic physics to life through a multimedia project including an interactive website, a facilitated program for museums and schools, and an educational outreach program.
Animated segments focus on the adventures of Ushi (up-quark), Danny (down-quark), and Harold (up-quark) as they take on the invisible world of particle physics in their proton subatomic universe vehicle (SUV). Each Quarked character has an animated human counterpart who learns ways to solve everyday problems through the Quarked! micro-world adventures.
Targeted to kids ages 7–12 (and their families), the Quarked! project plans also include an animated television series plus science-based toys and games featuring the Quarked! characters.
