Biodegradable poly-(D,L-lactide-co-glycolide) microspheres (PLGA-MS) are approved as a drug delivery system in humans and represent a promising antigen delivery device for immunotherapy against cancer. Immune responses following PLGA-MS vaccination require cross-presentation of encapsulated antigen by professional antigen presenting cells (APCs). While the potential of PLGA-MS as vaccine formul...

In situ forming delivery systems composed of block copolymers are attracting substantial attention due to their ease of use, biocompatibility, and biodegradability. In this study, the thermoresponsive triblock copolymer PLGA-PEG-PLGA was studied as a dexamethasone delivery system. Dexamethasone, a synthetic glucocorticoid, is used clinically to improve inflammation, pain, and the hyperemesis of...

Small molecule chemotherapeutics often have undesired physiochemical and pharmacological properties, such as low solubility, severe side effect and narrow therapeutic index. To address these challenges, polymeric nanomedicine drug delivery technology has been routinely employed, in particular with the use of biodegradable and biocompatible polyesters, such as poly(lactide) (PLA) and poly(lactid...

Poly(lactic-co-glycolic) acid (PLGA) has attracted a considerable amount of interest for biomedical application due to its biocompatibility, tailored biodegradation rate (depending on the molecular weight and copolymer ratio), approval for clinical use in humans by the U.S. Food and Drug Administration (FDA), the potential to change surface properties to create better interaction with biologica...

Abstract Research on cancer treatment is always of great importance because the extensive and difficult options side effects chemotherapeutic agents. Due to this, novel techniques for are need day. Nowadays, nanotechnology interest its applications as diagnostic tools, theragnostic, contrasting agents, vehicles delivering drugs. Nanoparticles (NPs) made up biocompatible biodegradable polymers t...

To solve the problem of synthesized magnetic nanoparticles in cancer therapy, a new drug delivery system synthesized from bacteria was used to load cytosine arabinoside (Ara-C). Genipin (GP) and poly-l-glutamic acid (PLGA) were selected as dual cross-linkers. The preparation and characterization of Ara-C-loaded GP-PLGA-modified bacterial magnetosomes (BMs) (ABMs-P), as well as their in vitro an...

Cancer is the leading cause of death worldwide. Nanomaterials and nanotechnologies could provide potential solutions. In this research, a novel biodegradable poly(lactide-co-glycolide)-d-a-tocopheryl polyethylene glycol 1000 succinate (PLGA-TPGS) random copolymer was synthesized from lactide, glycolide and d-a-tocopheryl polyethylene glycol 1000 succinate (TPGS) by ring-opening polymerization u...

The potential of PLGA-nanoparticles as a carrier of amphotericin B and doxorubicin against visceral leishmaniasis was evaluated by macrophage-mediated drug targeting approach. PLGA-nanoparticles were modified by coating them with macrophage-specific ligand-lectin. Prior to in-vitro studies, characterization studies were carried out systematically include particle size, surface morphology, perce...
