Functional polymeric systems have attracted increasing interest in recent years due to their considerable potential applications. During the last two decades, stimuliresponsive polymers and polymer composites have been developed, which respond to various external stimuli, such as pH, temperature, gas, light, chemical compound, electric or magnetic fields, and mechanical force. Such progress ensures their biorelated applications in self-healable/shape memory hydrogels, biomaterials and biosensors, diffractive lenses, tissue engineering, wearable displays, etc. In addition, industrial approaches with high reliability for the synthesis of well-defined polymers with tailored functionality are also important issues.

This special issue welcomes original research articles with a focus on the stimuliresponsive polymers for bioapplications, including simulation, design, synthesis, functionalization, and applications of the functional polymeric systems. Furthermore, review papers featuring progresses in related area are also welcomed.

Potential topics include but are not limited to the following:

• Next-generation polymer-based biosensors
• Biocompatible smart hydrogels or tissue engineering
• Stimuliresponsive photonic or shape memory materials
• Photoluminescent and optoelectronic composites for bioimaging
