Microcarriers can be made from a number of different materials including DEAE-dextran, glass, polystyrene plastic, acrylamide, collagen, and alginate.

It was produced in 1980 by making an alginate cast of a live, wild Kenyan elephant bull, which survived the 72 minute process unharmed.
43.
An example of the implementation of the IVB approach was in the engineering of autologous bone by injecting calcium alginate in a sub-periosteal location.
44.
Calcium alginate is used in different types of medical products including skin wound dressings to promote healing and can be removed with less pain than conventional dressings.
45.
Between 100, 000 and 170, 000 wet tons of " Macrocystis " are harvested annually in New Mexico for alginate extraction and abalone feed.
46.
Alginate absorbs water quickly, which makes it useful as an additive in dehydrated products such as slimming aids, and in the manufacture of paper and textiles.
47.
In dentistry, syneresis is the expulsion of water or other liquid molecules from dental impression materials ( Alginate for example ) after an impression has been taken.
48.
A more recent technique is frozen reverse spherification, which involves pre-freezing spheres containing calcium lactate gluconate and then submerging them in a sodium alginate bath.
49.
The impression may be obtained by using a specifically designed impression kit that uses dental putty, or from a dentist who will take an impression in dental alginate material.
50.
Calcium alginate, made from sodium alginate from which the sodium salt has been removed and replaced with calcium, has the chemical formula C 12 H 14 CaO 12.
