Abstract: Described are methods and devices for the generation of hydrogel particles with micrometer and submicrometer dimensions using oxygen-inhibited partial polymerization, and the particles generated therefrom. The described methods generate particles with dimensions independent of the starting polymerizable solution dimension, for example, a microdroplet. Further, microfluidic flow parameters (e.g. viscosity, flow rate) and photopolymerization process parameters (e.g. optical exposure intensity and duration) are controlled to generate particles with tunable crosslinking density-determined properties including elasticity, diffusivity, and biomolecular display for diverse applications such as drug delivery, tissue engineering cell scaffolds, and single- and multiple-cell therapeutics. Similarly, gradients of crosslinking density-determined properties can be created within single particles through the selection of optical exposure intensity and duration.

Abstract: A metal nuclide-loaded carbon microsphere (CMS), and a preparation method and a use thereof are provided. The preparation method includes: subjecting a metal ion and a small organic molecule to a reaction in an aqueous solution to obtain a complex; allowing a CMS to adsorb the complex; and subjecting the CMS adsorbing the complex to a first treatment.
