The Role of Calcium in the Human Body - …
Nearly all calcium in the body is stored in bones. Its role is to help bones to remain strong and stiff enough to carry the weight of the body. When needed, the body can draw upon these calcium reserves in the bones and use it elsewhere, such as in the bloodstream and soft tissues. Calcium is a mineral and so it cannot be produced by the body.
Microfluidic Electrospray Niacin Metal-Organic …
Niacin metal-organic frameworks (MOFs) encapsulated microcapsules with alginate shells and copper-/zinc-niacin framework cores were in situ synthesized by using a microfluidic electrospray approach for wound healing. As the alginate shells were bacteria-responsively degradable, the niacin MOFs encapsulated microcapsules could intelligently, controllably, and programmably release calcium
