Desorption-ionization mass spectrometry on porous silicon
Article Abstract:
A matrix-free method for biomolecular mass spectrometry is described, based on pulsed-laser desorption-ionization from a porous silicon surface, and using porous silicon to trap analytes. Laser irradiation is used to vaporize and ionize the analytes, and little or no fragmentation is induced. The method provides good sensitivity and compatibility with silicon-based microfluidics and microchip technologies.

Invisible circuits: Materials science
Article Abstract:
Physicists, chemists and engineers are constantly seeking new and improved materials for electronic circuits. Hiroshi Kawazo and colleages have described an invisible materials within which positive charges carry an electrical current. Its properties are characteristic of a doped semiconductor, and it is an important step towards new types of invisible circuits.
