Topical Collection Information
Dear Colleagues,
While inkjet printing has been applied as a surface functionalization process over the past decade, recent advances in structural, functional, and biological materials printing capabilities and processes provide new opportunities in biosensor design, fabrication, integration, and application. This Special Issue is dedicated to recent progress in 3D-printed biosensors. Original research articles reporting advances in 3D-printed biosensor transduction elements such as electrodes and stimuli-responsive materials, 3D-printed biosensor-integrated microfluidic systems such as biosensor-integrated tissue and organ chips, 3D-printed hydrogel-based biosensors, and applications of 3D-printed biosensors are encouraged. Related studies beyond these topics that report advances in 3D-printed biosensors and biosensing using 3D-printed platforms are encouraged.
This topic is central to describing the emerging landscape of manufacturing processes for biosensor fabrication, specifically expanding the use of additive manufacturing processes for biosensor design, fabrication, and application.

The widespread adaptation of 3D printing in the microfluidic, bioelectronic, and Bio-MEMS communities has been stifled by the lack of investigation into the biocompatibility of commercially available printer resins. By introducing an in-depth post-printing treatment of these resins, their biocompatibility can be dramatically improved up to that of a standard cell culture vessel (99.99%). Additionally, encapsulating resins that are less biocompatible with materials that are common constituents in biosensors further enhances the biocompatibility of the material. This investigation provides a clear pathway toward developing fully functional and biocompatible 3D printed biosensor devices, especially for interfacing with electrogenic cells, utilizing benchtop-based microfabrication, and post-processing techniques.
