Abstract:
A reactive particle comprising:a) a shell of crosslinked polymer, wherein the crosslinked polymer is bound to at least one reactive component selected from the group consisting of an enzyme, an enzyme substrate, an antibody, an antigen, biotin, streptavidin, RNA, and DNA, the crosslinked polymer reticularly enclosing b) a core of material having at least one property selected from the group consisting of absorptivity of electro magnetic waves, emissivity of electromagnetic waves, mass magnetism, dielectricity, radioactivity, size distribution, pharmacological activity, biological activity, and catalytic activity, the particle produced by the process comprising the steps of:reacting at least one crosslinkable polymer, wherein the crosslinkable polymer is bound to the at least one reactive component, with the material having at least one property to produce an intermediate comprising (i) the crosslinkable polymer enveloping (ii) a core of the material followed by reacting the at least one crosslinkable polymer with a crosslinking agent, at a ratio crosslinking agent/crosslinkable polymer of at least 10/1, to crosslink the polymer to form a molecular network and, thereby, reticularly enclose the core.
