Nature-inspired functional porous materials for low-concentration biomarker detection

Abstract

Nanostructuration is a promising tool for enhancing the performance of sensors based on electrochemical transduction. Nanostructured materials allow increasing the surface area of the electrode, and to improve the limit...

Inverse opals with reactive surface chemistry as sensors for aqueous pollutants

“…[12][13][14][15] Inverse opals (IOs), three-dimensional porous networks with fully interconnected, uniform pores, exhibit structural coloration visible by the naked eye due to the periodic nature of the nanopores. [16][17][18][19][20] When prepared using a matrix able to shrink upon interaction with an analyte, they can also act as colorimetric sensors. 21 Since structural coloration relies on a refractive index contrast between pore and matrix, 16 the infiltration of an IO with liquid eliminates the observable coloration because of the higher refractive index of liquids compared to air.…”
