A new difunctional recognition and nanocatalytic probe of copper metal-organic framework surface molecularly imprinted polyethyleneimine (CuMOF@MIP) was prepared by microwave procedure, using tert-butylhydroquinone (TBHQ) as the template molecule, CuMOF as the nanosubstrate and polyethyleneimine (PEI) as the functional monomer. The experimental results demonstrate that the CuMOF@MIP nanoprobes exhibit strong catalysis of acrylic acid reduction of silver nitrate to produce silver nanoparticles (AgNP) with surface plasmon resonance Rayleigh scattering (RRS) effect at 330 nm. The new nanocatalytic amplification indicator reaction was studied by RRS and coupled with the recognition function to develop a catalytic analysis strategy.

The behavior of silver nitrate in non-aqueous liquid oligomeric media-aromatic and aliphatic diglycidyl ethers and aliphatic diamine-has been investigated. By employing UV-visible spectrophotometry and dynamic light scattering, it has been shown that in diglycidyl oligomers, regardless of the nature of the monomeric unit, the formation of silver nanoparticles occurs, and the kinetics of this process has been studied. At the same time, in the medium of aliphatic diamine, the reduction of silver ions is absent, indicating the formation of a complex compound.

We present the synthesis and characterization of a hybrid material comprising silver nanoparticles embedded within a 3D hydrogel network. The use of an aqueous extract of Acanthus mollis as a natural reducing agent facilitates the synthesis process. Acanthus mollis is a perennial, invasive and leafy plant that is widely distributed across the planet.
