PROBLEM TO BE SOLVED: To provide bioerodible devices, such as implants for delivering therapeutic agents, in particular, large molecules such as proteins and antibodies, in a controlled manner.SOLUTION: The devices comprise a porous silicon-based carrier material impregnated with a therapeutic agent. The device may be used in vitro or in vivo to deliver the therapeutic agent, preferably in a controlled manner over an intended period of time such as multiple days, weeks or months.
