Fabrication of Zn‐MoO<sub>3‐<i>x</i></sub> Nanocrystals with Enhanced Plasmon Resonance for Biosensing Application
Doping with alien atoms or ions can efficiently tune the plasma resonance peak position of the metal oxide nanocrystals. While subjected to the instinct crystalline structure and the doping procedure, the ability of semiconductor to accommodate alien guest atoms or ions is limited. In this work, a novel protocol is proposed to fabricate Zn ion‐doped MoO 3 (Zn‐MoO 3‐ x ) nanocrystals with enhanced localized surface plasmon resonance (LSPR) properties and the plasma resonance peak position of the Zn‐MoO 3‐ x is located ranging from 400 to 1400 nm. Thus, the Zn‐MoO 3‐ x nanocrystals have been regarded as the proper candidate for the LSPR‐based biosensing of bovine serum protein (BSA). And the response factor can reach 2.8 when the concentration of BSA is 2 mg mL −1 .
