    Abstract: The present invention discloses a bioreactor that uses microwave tubes to pretreat starch based raw materials input into a microwave reaction chamber, which is beneficial for opening the starch crystal structure during liquefaction and hydrolysis. After microwave pretreatment, the substrate raw materials enter an ultrasonic reaction chamber and are sprayed for liquefaction. Ultrasonic radiation is used in combination with heating, mixing, and stirring to destroy enzyme activity, which is beneficial for enzyme activity activation and hydrolysis. The characteristic of using ultrasonic radiation for auxiliary modification of starch is high reaction efficiency and strong performance.

    Abstract: The present invention relates to the field of organic and analytical chemistry. To address issues of low selectivity, low sensitivity, and high cost in detecting different types of VOCs using existing technologies, this invention proposes an R6G@UiO-66-NH-CO-COOH fluorescent molecular probe, its preparation method, and its application. UiO-66-NH2 is prepared using ZrCl4, BDC-NH2, and DMF as raw materials. UiO-66-NH2 is then added to THF and TEA to obtain UiO-66-NH-CO-COOH. Finally, UiO-66-NH-CO-COOH powder is mixed with R6G, stirred, centrifuged, and dried to obtain R6G@UiO-66-NH- CO-COOH powder, which is the R6G@UiO-66-NH-CO-COOH fluorescent molecular probe. This is used to construct a ratiometric fluorescence sensor for detecting amine VOCs. The ratiometric fluorescence sensor constructed in this invention exhibits good selectivity for amine volatile organic compounds and can be used for detecting organic pollutants in the environment or indoor air.
