A method of protecting an in-vivo sensor includes forming a sensing surface on a surface of the in-vivo sensor, the sensing surface including a functionalized monolayer that will bind to an analyte of interest； and coating the sensing surface of the sensor with a bioabsorbable polymeric coating including a bioabsorbable polymer； wherein the bioabsorbable polymeric coating is configured to protect the in-vivo sensor until needed for implantation.
