Abstract Scope |
3Two photon polymerization is 3D printing technique that relies on the use of ultrashort laser pulses to polymerize and solidify photosensitive materials. The quadratic nature of the two photon absorption probability and the well-defined polymerization threshold of this technique allow one to overcome the diffraction limit and obtain structures containing features below one micrometer. Two photon polymerization has been to prepare medical devices out of biocompatible inorganic-organic hybrid materials and polymers. The use of biocompatible photoinitiators (e.g., a combination of riboflavin and triethanolamine) for two photon polymerization will be considered. Integration of electrochemical sensors with two photon polymerization-manufactured devices will be considered. Evaluation of two photon polymerization-manufactured materials using in vitro biological studies will be discussed. In addition, application-specific analysis of two photon polymerization-manufactured devices for biosensing and drug delivery will be discussed. |
