ALBUQUERQUE, N.M. -- A new coating for chemical sensors promises to increase their sensitivity by a factor of 500. The porous coating, developed at Sandia National Laboratories, is less than 1 µm thick, but its extremely high surface area makes the device more sensitive to dangerous or deadly chemicals such as the nerve gas Sarin. The regular arrangement of the pores on a new coating developed by Sandia National Laboratories acts as a tiny filter and can enhance the sensitivity of chemical sensors. According to principal investigator Jeff Brinker at Sandia, the highly hydrophobic porous...Read full article
