Abstract

The invention belongs to the technical field of nano-material preparation and bacterial infection resistance, and relates to a glucose oxidase and hemoglobin loaded nano-reactor and a preparation method and an application thereof, the structure of the nano-reactor is a zeolite imidazate skeleton structure simultaneously loading glucose oxidase and hemoglobin, and the nano-reactor can be applied to bacterial infection resistance, and particularly, bacterial infection of wounds of diabetics can be controlled, and wound healing is promoted; the nano-reactor has good biocompatibility and environmental friendliness, is more remarkable in antibacterial effect, can achieve a good antibacterial effect without adding exogenous hydrogen peroxide, has a remarkable bactericidal effect on methicillin-resistant staphylococcus aureus and escherichia coli producing extended-spectrum beta-lactamase, and can efficiently promote the wound healing caused by multi-drug-resistant bacterial infection of the diabetics, and the market prospect is extremely wide.

Description

Technical field: [0001] The present invention belongs to the nanomaterial preparation and antibacterial infection technology, which relates to a nano-reactor having a negative glucose oxidase and hemoglobin and a preparation method and application thereof. Based on the metal organic frame structure through the package method load-bearing catalytic system, high The catalytic active nano reactor has a significant increase in activity than natural enzyme activity, which can control multiple drug-resistant bacterial infections, and promote the healing of diabetic wounds. Background technique: [0002] At present, bacterial infection is a common complications in patients, which seriously affects the recovery of surgery patients, and has caused a heavy economic burden. Diabetes patients, due to its high blood sugar levels, can provide sufficient nutrients for bacteria, so the healing of diabetes patients has more difficulties. Escherichia coli and golden Staphylococcus aureus are commo...
