Abstract:
In this paper, we report a green and controllable synthetic method of gold nanoparticles (AuNPs) by directly β-CD reduction under mild conditions. Analysis of UV-vis spectra, along with TEM was applied to study the effects of experimental parameters on morphologies of the gold nanoparticles. The corresponding formation mechanism of the nanoparticles was evaluated by redox potential. In particular, compared with the traditional method of sodium citrate or ascorbic reduction, this method can facilely realize multi-dimensional regulation. On this basis, we further studied the dispersion behavior of the as-prepared gold nanoparticles in oil/water mixed system that would provide a possible strategy for optical sensor.

States of Water
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
