Embodiment 1

[0030] Place 1 gram of SiO in the middle of the alumina furnace tube of the horizontal tube furnace, then evacuate the alumina furnace tube to 1 Pa, and then pass a mixed gas of argon and hydrogen into the alumina furnace tube, wherein the hydrogen content accounts for 5% of the volume of the mixed gas. The air pressure of the alumina furnace tube was stabilized at 1000 Pa. Then the temperature of the tube furnace was raised to 1350° C., and after maintaining the temperature for 6 hours, the temperature of the tube furnace was naturally cooled. Finally, one-dimensional silicon nanowires are obtained in the tube furnace, and the diameter of the one-dimensional silicon nanowires is 8 nm to 10 nm, and the length is 1 μm to 10 μm. see figure 1 .

Abstract

The invention relates to a fluorescent molecular machine based on one-dimensional silicon nanowires and a using method thereof. The fluorescent molecular machine based on one-dimensional silicon nanowires consists of one-dimensional nanowires modified by 3-aminopropyltriethoxysilane, as well as N,N-bis-(4-p-formylphenylazobenzene-4'-methyl)-dansylamide and alpha-cyclodextrin, wherein the alpha-cyclodextrin is sleeved on the N,N-bis-(4-p-formylphenylazobenzene-4'-methyl)-dansylamide, and the N,N-bis-(4-p-formylphenylazobenzene-4'-methyl)-dansylamide is bonded with the one-dimensional nanowires modified by the 3-aminopropyltriethoxysilane by covalent bonds. In the invention, ultraviolet light and visible light are used as input to control the motion of the fluorescent molecular machine and fluorescence is used as output to demonstrate the motion of the fluorescent molecular machine.

Description

technical field [0001] The invention belongs to the field of fluorescent molecular machines with one-dimensional nanostructures, in particular to a fluorescent molecular machine based on one-dimensional silicon nanowires, and a method for preparing and using the fluorescent molecular machine based on one-dimensional silicon nanowires. Background technique [0002] For a long time, scientists have been hoping to develop ultra-miniature machines in the nanoscale range, hoping to use them for dredging blood vessels or repairing damaged tissues. In cooperation with German scientists, France and Germany successfully developed a rotatable "molecular wheel" for the first time, and assembled the first fluorescent molecular machine in the true sense-bio-nano fluorescent molecular machine, which opened the prelude to the research of fluorescent molecular machines. Since then, researchers have prepared a variety of fluorescent molecular machines, including dumbbell-shaped molecular ele...
