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 number1800084, 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.
