Albumin nanoparticles (HSA-NPs) represent a promising platform for drug delivery in cancer therapy due to their biocompatibility, biodegradability, and ability to transport hydrophobic drugs. Encapsulation of chemotherapeutic agents within these nanoparticles enhances solubility, stability, and targeted release to tumor cells while reducing systemic side effects. In this study, albumin nanoparticles functionalized with manganese dioxide (MnO₂) and loaded with antitumor drugs such as salinomycin (SAL) and fenretinide (4-HPR) were analyzed in vitro to assess their biocompatibility and therapeutic potential as an immunomodulatory agent in the tumor microenvironment. The results obtained represent an initial step in the characterization of these nanoparticles, laying the groundwork for future in vivo studies.
Le nanoparticelle di albumina (HSA-NPs) rappresentano una piattaforma promettente per il drug delivery nella terapia del cancro grazie alla loro biocompatibilità, biodegradabilità e capacità di trasportare farmaci idrofobici. L'incapsulamento di agenti chemioterapici all'interno di queste nanoparticelle migliora la solubilità, la stabilità e il rilascio mirato alle cellule tumorali, riducendo al contempo gli effetti collaterali sistemici. In questo lavoro, sono state analizzate nanoparticelle di albumina funzionalizzate con diossido di manganese (MnO2) e caricate con farmaci antitumorali quali salinomicina (SAL) e fenretinide (4-HPR) per caratterizzarne in vitro la biocompatibilità e il potenziale terapeutico come agente immuno-modulatorio nel microambiente tumorale. I risultati ottenuti rappresentano un primo passo nella caratterizzazione di queste nanoparticelle, ponendo le basi per futuri studi in vivo.

Abstract
Albumin nanoparticles (HSA-NPs) represent a promising platform for drug delivery in cancer therapy due to their biocompatibility, biodegradability, and ability to transport hydrophobic drugs. Encapsulation of chemotherapeutic agents within these nanoparticles enhances solubility, stability, and targeted release to tumor cells while reducing systemic side effects. In this study, albumin nanoparticles functionalized with manganese dioxide (MnO₂) and loaded with antitumor drugs such as salinomycin (SAL) and fenretinide (4-HPR) were analyzed in vitro to assess their biocompatibility and therapeutic potential as an immunomodulatory agent in the tumor microenvironment. The results obtained represent an initial step in the characterization of these nanoparticles, laying the groundwork for future in vivo studies.| File | Dimensione | Formato | |
