Nanotechnology and biotechnology are the two leading technologies of the 21st century, and there are many technical intersections between the two. Among them, nano biosensing technology is expected to become an emerging industry. It is a research field formed by the mutual penetration of various disciplines such as biology, chemistry, medicine, physics and electronic technology. Nano biosensors are characterized by high selectivity, fast analysis, easy operation and low price. They can be used for online and even live analysis, and have been highly valued and widely used in clinical diagnosis, environmental monitoring, and food industry. In the past research, the introduction of nanotechnology into the field of biosensors has improved the sensitivity and other properties of biosensors and led to new biosensors. Thanks to submicron-sized transducers, probes or nano-microsystems, the performance of biosensors has increased dramatically. According to the internationally renowned journal Advanced Materials, Zhao Yongsheng, a key laboratory of the Institute of Chemistry, Institute of Chemistry, Chinese Academy of Sciences, has prepared a more advanced reusable electrochemiluminescence nanobiosensor. As a valuable detection device, electrochemiluminescence nanobiosensors have received more and more attention in detection applications. Electrochemiluminescence has high stability and low background signal, so electrochemiluminescence has attracted great interest from scientists. At the same time, renewable electrochemiluminescence sensors have been extensively studied because such regenerative sensors not only reduce the consumption of reagents, but also simplify the experimental design. The nanomaterials electrochemically oxidized and reduced can react with the co-reactant on the surface of the electrode to produce electrochemiluminescence. The researchers in this group introduced ruthenium pyridine (Ru(bpy)32+) nanowires as luminescent probes in the electrochemiluminescence sensing system, and enhanced the electrochemiluminescence by reducing graphene oxide (RGO). Efficient and sensitive detection of biomolecular dopamine. This study also demonstrates that high specific surface area 1D nanomaterials can be used to prepare electrochemiluminescent sensors, which may result in higher sensitivity, smaller size, faster response, and the need for samples to be tested. less. After that, the research team prepared nano-biosensors with organic core/shell nanostructures. The researchers used 9,10-diphenylethynyl ruthenium (BPEA) single crystal nanowires as the core layer, and the H2O2-sensitive peroxy oxalate derivative CPPO as the shell layer. The chemiluminescence experiment proved the shell layer to H2O2. Gases have an ultrasensitive and highly selective response. On this basis, the scientists also used the evanescent wave coupling between the core shells to effectively amplify the chemical reaction of CPPO and H2O2 gas, and constructed the BPEA@CPPO optical waveguide sensor, thus achieving fast and high sensitivity to H2O2 gas. Highly selective in situ detection. This study further highlights the use of high specific surface area of ​​one-dimensional nanomaterials to prepare biosensors that can increase sensor sensitivity. Researchers at the lab stressed that these findings provide important theoretical and experimental evidence for the study of biosensors for low-dimensional nanomaterial preparation. Next, they will use one-dimensional nanomaterials to construct nanophotonics biosensor-related devices to achieve the perfect combination of nanomaterials, photonics and biology.
