Interest in utilizing biodegradable polymers for biomedical applications has grown since the 1960s.

The world of commercial biomaterials has stagnated over the past 30 years as few materials have successfully transitioned from the bench to clinical use. Synthetic aliphatic polyesters have continued to dominate the field of resorbable biomaterials due to their long history and track record of approval with the U.S. Food and Drug Administration (FDA).

Aliphatic polyesters such as polylactide, poly(lactide-co-glycolide) and polycaprolactone, as well as their copolymers, represent a diverse family of synthetic biodegradable polymers that have been widely explored for medical uses and are commercially available.

Immunosuppressive tumor-associated myeloid cells (TAMC) are responsible for glioblastoma (GBM) resistance to immunotherapies and existing standard of care treatments. This mini-review highlights recent progress in implementing nanotechnology in advancing TAMC-targeted therapies for GBM.
