Point-to-Point Adsorption Creates Ordered Gold Nanoparticle Arrays for Memory Devices

Caption

Scanning electron microscopy image showing a ordered non-close-packed array of gold nanoparticles (inset: FFT pattern demonstrating hexagonal ordering). Schematic illustration of the point-to-point adsorption mechanism, where protonated P4VP cores in block copolymer micelles capture individual citrate-stabilized gold nanoparticles through electrostatic interactions, forming a precisely ordered monolayer suitable for nano-floating-gate memory applications.
