Summary: This article reviews the use of biodegradable polyesters for drug-loaded implants, discussing their properties, formulation techniques, release mechanisms, and clinical applications. Drug delivery implants provide safe and sustained drug release with high bioavailability and low toxicity. Depending on the design and deployment site, they can offer localized or systemic drug release. Polyester-based implants represent an important class of controlled release technologies due to their long history of use and are the largest category of drug delivery implants tested or approved for human use.

Summary: Due to the life-threatening side effects of microbial infections, conventional anti-infective therapy is not sufficient. This has led to the urgent need for advanced antimicrobials and antimicrobial devices. The development of biostatic or biocide agents and biomaterials using biopolymers has been successful in overcoming these limitations. Biopolymers have attractive properties and can be used as carriers for drug delivery and can be processed in different forms for modern anti-infective applications.

Summary: This study presents an innovative synthesis strategy to overcome the low reactivity of secondary diols in polyester synthesis, enabling the production of fully biobased polyesters with high molecular weights. The addition of an aryl alcohol during esterification promotes chain growth and facilitates the formation of high molecular weight polyesters. This method has broad applicability for aliphatic polyesters based on isosorbide and isomannide, and could be a significant step towards the commercialization of fully biobased, rigid polyesters.

Summary: This study investigates the antibacterial and antibiofouling properties of bioinspired high aspect ratio nanostructures generated on poly(ethylene terephthalate) (PET) surfaces. The results show that these structures effectively neutralize Gram-negative bacterial contamination but are unable to inactivate Gram-positive cells. The clustering of the soft, flexible tall nanopillars enhances the stiffness of the structures, and external capillary forces improve the killing efficiency. Additionally, experimental and computational investigations demonstrate the durability of the nanostructured surfaces against daily life forces.
