Ordered ellipsoid templates are successfully fabricated in the air–liquid interface and induced by magnetic field. The influence factors on ordered structures are investigated and evaluated by SEM and reflective spectra. The optimal conditions are determined by different self-assembly processes and optical analyses.

Structural Composite

A robust and effective nanocomposite film modified gold electrode based on 2, 3-dimercaptosuccinic acid (DMSA) and Au nanoparticles (AuNPs) was prepared by a method combining self-assembly with underpotential deposition. Direct electron transfer can easily take place between a gold electrode and catalase molecules anchored on AuNPs films. Besides, the CAT/AuNPs/DMSA multilayer film had a relatively rapid and satisfactory response toward H2O2 with a wide linear range from 3.0×106 to 5.86×103 M and a low detection limit of 3.0 μM (S/N = 3). The Michaelis-Menten constant of the immobilized CAT was calculated to be 2.2 mM. The simple CAT/AuNPs/DMSA/Au system can be developed into a H2O2 biosensor.
