Scientists at the Weizmann Institute of Science describe a novel oligonucleotide, also known as an Aptamer, which has been designed to complement the receptor-binding region of the influenza haemagglutinin molecule. It was constructed by screening a DNA library and processing by the SELEX procedure......

Electrostatic resonators are building blocks in filters, sensors, oscillators and many other devices. Linear electrostatic resonators commonly have a high quality factor, making their resonance peak sharp. A very high sensitivity to frequency may also be obtained from nonlinear resonators. It is wel.....
