▎ 摘　　要

NOVELTY - All-solid nanoprobe comprises a glass tube and solid polymer, which is filled in the glass tube, and the solid polymer is obtained by free radical polymerization of monomers and a photoinitiator, and the monomer comprises acrylamide, hydroxyethyl acrylate and polyethylene glycol diacrylate. USE - The all-solid-state nanoprobe is useful in detection of graphene and its analogue samples (claimed), and used for scanning electrochemical cell microscope. ADVANTAGE - The all-solid-state nanoprobe solves the contradiction between high electrochemical resolution and high spatial resolution, suspends solid pellets by needle tip with more stable shape and has excellent electrochemical performance similar to that of droplets, and improves the resolution of scanning electrochemical cell microscope. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing the all-solid nanoprobe, involving (a) using glass tube as mold, and drawing the glass tube by P-2000 pull needle instrument, (b) adding the solid polymer to glass tube, and (c) after pouring solid polymer to mold, pressurizing the mold using air pump, performing UV illumination polymerization under pressurization condition, turning off light source after illumination, and releasing air pressure. (2) use of the all-solid-state nanoprobe in detection of graphene and its analogue samples.
