Abstract
The invention discloses a method for preparing and siliconizing DNA nano optical fibers and characterizing the surface microstructural components of the siliconized nano optical fibers, which can visually represent the covalent grafting on the head parts of the optical fibers, and is characterized in that: micron-sized optical fibers are etched in an etchant for 5 hours to form the nano optical fibers; the optical fibers are placed in 10 weight portions of silane solution to react for 1 to 5 hours under the conditions of a temperature of between 60 and 90 DEG C and a pH value of between 2 and 4.5; and the optical fibers are taken out, washed by distilled water and dried for 10 to 12 hours under vacuum and at 90 to 100 DEG C. The result of nano optical fiber surface microstructural component detection by the method shows that the method can be used for detecting the surface microstructural components of the siliconized optical fibers and can visually characterize the coupling between bioactive molecules and the siliconized optical fibers.
Description
technical field [0001] The invention relates to a preparation and characterization technology of a core sensitive element of a micro-nano optical fiberbiosensor and a technical route for its realization. The technology is applied in the fields of environmental monitoring, biomedicine and clinical testing equipment manufacturing and the like. Background technique [0002] As the medium or sensitive element of the sensor, nano-fibers together constitute nano-fiber sensors, such as nano-fiber biosensors, which can be applied to non-invasive or micro-trauma in vivo or intracellular, real-time and remote online medical diagnosis, online Quality monitoring and environmental testing. For example, nano-fiberDNA biosensors can quickly and effectively detect special gene sequences and point mutations. Due to the strong anti-electromagnetic interference and optical signals of optical fibers, no additional reference devices are required for measurement [Mara Dolores Marazuela, Mara C...
