Acrylic Microspheres-Based Optosensor for Visual Detection Of Nitrite

A new optosensor for visual quantitation of nitrite (NO2−) ion has been fabricated by physically immobilizing Safranine O (SO) reagent onto a self-adhesive poly(n-butyl acrylate) [poly(nBA)] microspheres matrix, which was synthesized via facile microemulsion UV lithography technique. Evaluation and...
