Definitions

  • Gel particles can be formed by adding a scavenger and an MRP to a solution of liquefied gel (e.g., sodium alginate) to form a suspension, and then expanding the suspension through an air jet. Gel particles can also be formed using emulsification, dripping and Rayleigh jet. Methods of preparing a gel particle containing a cell are disclosed in, for example, U.S. Patents No. 4,701,326; 5,567,451; and 5,846,530.
