With the help of Internet, Massive Open Online Courses (MOOC) are recognized as a new path to learn courses via the web instead of in the traditional classrooms. MOOC can break many limits such as distance, time, participants, on the traditional courses. At the same time, it brings some new issues, such as high drop out ratio. Nowadays increasing MOOC(More)
A novel ratiometric fluorescence nanosensor for superoxide anion (O2•- ) detection was designed with gold nanoparticles-bovine serum albumin (AuNPs-BSA)@terbium/guanosine monophosphate disodium (Tb/GMP) nanoscale coordination polymers (NCPs) (AuNPs-BSA@Tb/GMP NCPs). The abundant hydroxyl and amino groups of AuNPs-BSA acted as binding points for the(More)
This paper considers the Slepian-Wolf coding based energy-minimization rate allocation problem in a wireless sensor network (WSN) and propose a distributed rate allocation algorithm to solve the problem. The proposed distributed algorithm is based on an existing centralized rate allocation algorithm which has a high computational complexity. To reduce the(More)
The study was designed to examine the interaction between 2-(4-methylphenyl)-3-(N-acetyl)-5-(2,4-dichlorophenoxymethyl)-1,3,4-oxodiazoline (MPNDO) and bovine serum albumin (BSA) under physiological conditions by using fluorescence spectroscopy, ultraviolet absorption spectroscopy, FT-IR spectroscopy and circular dichroism spectroscopy and atomic force(More)
An easy and effective strategy for synthesizing a ratiometric fluorescent nanosensor has been demonstrated in this work. Novel fluorescent BSA-AuNPs@Tb-AMP (BSA, bovine serum albumin; AMP, adenosine 5'-monophosphate; AuNPs, Au nanoparticles) metal-organic framework (MOF) nanostructures were synthesized by encapsulating BSA-AuNPs into Tb-AMP MOFs for the(More)
Water-soluble fluorescent quantum dots (QDs) have been widely used in biological and biomedical fields, and the interaction between QDs and proteins and the conformational structure of the protein in the bioconjugate has attracted increasing attention. In this study, UV-Vis spectroscopy, fluorescence quenching, CD spectra, gel electrophoresis and Fourier(More)
Better understanding of the interaction between nanoparticles (NPs) and protein is the basis for biological and biomedical applications of NPs. Water-soluble fluorescent CdS NPs have been widely used in the biological and biomedical fields and the study on effect of CdS NPs size on conformation and enzymatic activity of protein might be very important in(More)
