Phenol red dye (PR) functionalized mesoporous silica matrix nano-structures/ nano-tubes (MSNs) are synthesized by sol-gel method for pH sensing. FE-SEM analysis revealed formation of different nano-objects (i.e. nano-clusters and nano-tubes) with defined pores, which are arranged into bunch of nanot...
