Thermally expandable microspheres are applied to the photocuring 3D printing technology for the first time; photocuring polyurethane having reversible bond structure end-capping is further synthesized; after the photocuring polyurethane is heated to a certain temperature, reversible bonds are broken, and the cross-linked structure is partially damaged, so that a sufficient space is provided for subsequent foam generation and growth while certain mechanical strength is maintained. In the present invention, a foaming resin is subjected to 3D stacking and curing, and then is subjected to foaming treatment, the pre-treatment does not need to be carried out on the resin, and the post-treatment is simple and fast, so that the product has low density and large foaming ratio, and the mechanical property of the foaming resin can be freely regulated and controlled without changing the 3D printing process.

This invention relates to a rare earth nanomaterial labeled biomolecule, its labeling method and a dissolution-enhanced time-resolved fluoroimmunoassay based on the rare earth nanomaterial. The rare earth nanomaterial serves as a label having stable properties, large specific surface area, strong modifiability, low-cost and thousands of lanthanide ions contained in each nanocrystal, the labeling ratio of rare earth ions can be greatly improved. Furthermore, the rare earth nanomaterial can be less affected by exogenous rare earth ions, unaffected by anticoagulants, and has broader applicability; after the immune complex was formed by labeling the biomolecules with the nanomaterial containing rare earth, an enhancer solution was added to allow the rare earth nanomaterial to dissolve into the rare earth ions, which can in turn form new signaling molecules with the chelates in the enhancer solution to induce intramolecular and intermolecular energy transfer, thereby significantly increasing fluorescence intensity by about a million times to greatly enhance the detection sensitivity by using time-resolved fluorescence assay.
