Abstract: The present invention relates generally to the field of cell culture, which is a laboratory process used primarily for the growth, propagation, and production of cells for analysis and the production and harvesting of cell products. The present invention comprises functionalized and/or engineered hydrogel microcarriers that exhibit any or all of the following properties: controllable buoyancy, ferro- or paramagnetism, molecular or fabricated reporting elements, and optical clarity. The microcarriers are used in a bioreactor that employs external forces to control said microcarrier kinetic energy and translational or positional orientation in order to facilitate cell growth and/or cellular analysis. The bioreactor can be part of an automated system that employs any or all of the following; a microcarrier manufacturing method, a monitoring method, a cell culture method, and an analytical method.
