Microresonators: Tetrasulfide‐Functionalized Mesoporous Silica on Nanowire Ring Resonators for Detection of Aqueous Lead, Pb(II) (Adv. Sustainable Syst. 1/2019)
Source abstract
Abstract
The image shows a false colour photograph of two optical micro-ring resonators made from silicon nanowires that are used in a miniature chemical sensor for lead, Pb(II). In article number 1800084, Hans-Peter Loock and co-workers coat the larger sensor with tetrasulfide-functionalized mesoporous silica to bind dissolved lead ions. The resulting refractive index increase of the coating is then observable through an optical resonance frequency shift.
