Iowa State scientists demonstrate first use of nanotechnology to enter plant cells
...cle system. Spherical in shape, the particles have arrays of independent porous channels. The channels form a honeycomb-like structure that can be filled with chemicals or molecules. "One gram of this kind of material can have a total surface area of a football field, making it possible to carry a large ...Magnetic computer sensors may help study biomolecules
...ed in a recent paper,* NIST researchers found that arrays of switches called "spin valves"—commonly used as ...or controlled trapping of single biomolecules. The arrays might be used in chip-scale, low-power microfluidic devices for stretching and uncoiling, or capturi......ds of tiny protein fragments. Traditionally, these arrays are used for finding binding sites within well-behaved proteins. Here, Tessier designed the arrays so that he could observe protein folding and amyloid formation in real time. Tessier covered the...
