Provided are a co-immobilized enzyme, a preparation method and use thereof. The co-immobilized enzyme includes: an amino resin carrier, a main enzyme, and a coenzyme. The main enzyme and the coenzyme are co-immobilized on the amino resin carrier, herein the main enzyme is covalent-immobilized on the amino resin carrier, and the coenzyme is immobilized on the amino resin carrier by a mode of covalent and/or non-covalent; and the main enzyme is selected from any one of the following enzymes: transaminase, amino acid dehydrogenase, imine reductase, ketoreductase, enoyl reductase, and monooxygenase. The main enzyme and the coenzyme thereof are co-immobilized on the amino resin carrier for co-immobilization, so the activity and the recycling efficiency of the enzyme are improved.

The present invention relates to methods of detecting a neural injury biomarker in a biological sample. The method includes subjecting a biological sample to an assay according to the present invention that produces a measurable signal and detecting the measurable signal. The presence or absence of the measurable signal indicates the presence or absence of the biomarker in the sample. The present invention also relates to methods of determining the state of a subject's neural injury. The present invention also relates to systems and devices useful in carrying out the methods of the present invention.

The present invention provides compositions and methods for reducing microbial contamination or infection in plants, animals, fabrics, and products therefrom. The present invention also provides compositions and methods for reducing human infections. In particular, it provides solid magnetic nanoparticles comprising bacteriostatic, bactericidal, fungistatic, or fungicidal enzymes in one component, and substrates for the enzymes in another component. The compositions are dormant and become active upon exposure to hydration and oxygen.
