Polymer Based Bio-Sensors II

Dear Colleagues,

The inherent biocompatibility and the unique optical, electrical, and mechanical properties of polymers have attracted attention from various fields, such as energy, as well as environmental and bioapplications. Especially, polymer-based biosensors, including enzyme-, tissue-, DNA-, aptamer-, and protein-based biosensors, have been rapidly developed, owing to their high performances. There are various detection methodologies for polymer-based biosensors, including electrochemical, optical, field-effect transistor, lateral flow assay, etc. Moreover, polymer-related materials, such as conducting polymer nanomaterials, polymer composites, polymer beads, and hybrids, have been designed and created. Although biosensors with these conventional polymers showed high-performance sensing properties, the challenges remain to enhance a maximum detectable level (MDL) of biosensors: (i) enlarged surface to volume ratios; (ii) development of interfacing chemistry, including surface modification and interfacial adhesion; (iii) high stability from surrounding environments; (iv) novel sensing systems, and so on. In addition, industrial approaches with high reliability in a multitude of fields are also important issues. Notably, polymer-based biosensors for healthcare monitoring have been investigated and integrated into smart devices to collect a large amount of sensing data.
This Special Issue invites original papers and reviews reporting on recent progress in the following areas:

- Fabrication methods of the polymers with enlarged surface areas and their biosensor applications;
- Chemical and physical surface modification of polymers to improve sensing performances;
- Next-generation polymer-based biosensors;
- Integration process of polymer-based biosensors into smart devices and their point-of-care test;
- Properties of polymer-based biosensors;
- Biological properties of polymer-based biosensors.
