Organic?inorganic hybrid nanomaterials offer
extremely valuable tools for monitoring many types of analytes
in solution. Within this framework, aptamer-based nanomaterials for heavy metal detection are still very scarce. Herein, a
novel sensing nanoprobe for the selective and sensitive
detection of As(III) based on the combination of aptamers
with mesoporous silica nanoparticles has been developed. The
efficiency of the sensor is demonstrated in environmental
conditions, showing a great potential in As(III) monitoring
assays
