Nanotechnology, the manipulation of matter on a molecular and atomic scale, is being used by scientists for a variety of purposes, including preventative treatments for cancer.
Self-assembled nanobots composed of biological components walk along tracks of DNA on an origami framework. The track of DNA is clipped by the bot as it walks, so that it can only go in one direction. Created for the opener of Science News Magazine using ZBrush and Photoshop.
Inside a tumor, nanospheres target receptors on the blood vessels and on the cancer cells themselves. Once bound, the nanospheres begin to release their drug and are engulfed by the cancer cells where the drug can attack the cancer cell from inside. Rendered in ZBrush and Modo, painted in Photoshop for BIND Biosciences.
A carpet of nanowires transmit light. By controlling the self-assembly of nanowires and their orientation, researcher Peidong Yang and his colleagues have created devices such as a wire that fires ultraviolet laser light. Digitally painted for the National Science Foundation.
Biosensors are able to detect minute molecules to help us monitor our health and our environment. Scientists are developing sensors that are sensitive enough to detect even the smallest presence of molecules, so that disease or dangerous environmental contaminants can quickly be assessed. Researchers at PC Rossin's school of engineering at Lehigh University have created a tiny glass slide of sliver with protein receptors applied to it. When the receptors bind with their matching signal molecule, light waves traveling across the chip are perturbed into a recognizable interference pattern. Using this combination of light waves and biomolecules has resulted in a biochip a magnitude more sensitive than other current comparable sensors. Created with 3D software and digital painting (Cinema 4D, Adobe Photoshop, and Illustrator).
Chips with nanotubes attached that can bind antibodies to sense specific diseases could be a fast screening test for disease. Digitally painted for CR magazine.
A microchannel designed to help sort self-assembled nanoparticles is shown in this 3d painting.
Cancer biologists are harnessing nanotechnology to help target chemotherapy directly to cancer cells and malignant tumors. Digitally painted for CR Magazine.
