Uniform arrays of nanochannels were made using an underexposed nanoimprint method. The nanotrenches were bended uniformly, and the degree of the collapse was controlled by the exposure time. After deposition of the sealing material, nanochannels with a dimension of 100 nm were successfully fabricated. The blocking problem was solved by adjusting the parameters of the gratings. The proposed fabrication...
Graphene, an extended conjugated system, is an efficient fluorescence quencher for various organic dyes and quantum dots. In this Letter, rhodamine 6G (R6G) was used as a typical representative probe molecule to investigate the interaction between graphene and cationic organic dye. The as-prepared graphene oxide and graphene were characterised by UV??vis spectroscopy, infrared spectroscopy and atomic...
