Microcarriers have historically been used to grow a number of adherent cell types for a variety of applications.

A variety of microcarriers have been designed, primarily differing in their choice of material and macroporous structure. Key concerns have been cell attachment at the beginning of culture and cell detachment at the harvesting step; these have largely driven the nature of the material and structures -employed. Many microcarriers simply use polystyrene (the material used for -tissue culture flasks and dishes in general) with no modification (SoloHill -Plastic, Nunc Biosilon), with a cationic surface charge (SoloHill Hillex) or -coated with an \gls{ecm} protein such as collagen (SoloHill Fact III). Other -base materials have been used such as dextran (GE Healthcare Cytodex), cellulose -(GE Healthcare Cytopore), and glass (Sigma Aldrich G2767), all with none or -similar surface modifications.

In the case of non-protein materials, cells may still be detached using enzymes but these require similar methods to those currently used in flasks such as trypsin which target the cellular \gls{ecm} directly. Since trypsin and related enzymes tends to be harsh on cells, an advantage of using entirely protein-based microcarriers is that they can be degraded using a much safer enzyme such as collagenase, at the cost of being more expensive and also -being harder to make \gls{gmp}-compliant. Going one step further, some -microcarriers are composed of a naturally degrading scaffold such as alginate, -which do not need an enzyme for degradation but are limited in that the -degradation process is less controllable.
