ABSTRACT
The surface properties of biodegradable polymers need adjustment through specific treatments in order to fulfill the criteria imposed by biomaterials. A good starting point for developing an efficient biocompatible material relies on treating the surface of a material that already displays good biofunctionality and bulk characteristics. In this way, its applicability is extended in various domains, such as bioengineering, microfluidics, textiles, bioelectronics, etc. Continued innovations in surface engineering led not only to novel processing routes of biodegradable polymers but also to new investigation techniques that emphasize the peculiarities created on their surfaces. Advancements regarding the processing and modification methodologies used in polymer science are described. Also, some relevant analysis tools for surface properties are shortly reviewed. The practical importance of surface modification of biodegradable biopolymers in food packaging, biosensors, and medicine is briefly presented, highlighting the future perspectives for the next generation of biomaterials with biodegradability and tuned surface features.
