The present study explores a therapeutic strategy that combines immuno- and photothermal therapies (PTT) using hybrid polymer-metal nanoparticles (NPs) to modulate the pancreatic tumor microenvironment, leading to sustained therapeutic efficacy. Core-satellite particles constituted of gold nanorods grafted at the surface of polylactic polyethylene block copolymer particles were designed to encapsulate a potent PI3K-γ inhibitor. The release of the drug from the particles was controlled by near-infrared laser irradiation power and time, offering versatility in controlling dosage profile noninvasively over 96 h. In vitro, 2D cultures of pancreatic cancer cells (KPC) exhibited significantly higher uptake of the hybrid nanoparticles compared to proinflammatory (M1) and anti-inflammatory (M2) macrophages. Consequently, KPC cells were more sensitive to PTT and could be eradicated while maintaining macrophages' viability. Through the photostimulated release of the PI3K-γ inhibitor, the particles effectively repolarized M2 macrophages to the M1 phenotype, enhancing cancer cell eradication. These positive outcomes were further confirmed on 3D cocultures of KPC and macrophage spheroids. Additionally, we showed that macrophages exposed to the nanoparticles exhibited sustained antitumor activity when repeatedly put in contact with cancer cells, confirming the long-term efficacy of the treatment. This study highlights the potential of the present polymer-metal hybrid nanoparticles as a versatile platform for combined immuno- and photothermal therapy in PDAC.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbial strategies offer considerable promise for ecofriendly bioenergy generation. This study presents an advanced integrated approach that combines bacterial treatment with a bioelectrochemical system (BES) to enhance the conversion efficiency of lignocellulosic biomass. Unlike integrated or sequential approaches, a comparative evaluation of two distinct pretreatment strategies, alkaline delignification and biological treatment, was conducted independently to assess their individual effectiveness in sugar cane bagasse (SCB) degradation and their performance in a microbial fuel cell (MFC). Biological treatment with <i>B. subtilis</i> alone yielded superior outcomes in terms of saccharification efficiency, microbial growth, and bioelectricity generation, as evidenced by higher open-circuit potentials in MFC half-cell studies in comparison with alkali delignified SCB. Notably, <i>B. subtilis</i> treatment increased cellulose content by 72% and reduced hemicellulose and lignin by approximately 0.84-fold, indicating effective enzymatic action. Metabolomic profiling identified 2846 metabolites that significantly diverged between the experimental groups. Notably, lignin-derived compounds such as ferulic acid, syringic acid, and p-coumaric acid were detected at elevated levels, confirming enhanced ligninase activity in pretreated SCB. Additionally, the presence of organic acids (e.g., acetic acid), amino acids, and their derivatives, resulting from the breakdown of cellulose, hemicellulose, and lignin, provided essential bioenergy substrates for exoelectrogenic organisms in BESs. This integration led to a maximum power density of 353 ± 5 mW/m<sup>2</sup> and a current density of 200 ± 3 mA/m<sup>2</sup>, demonstrating significant enhancement in performance of MFC.

However, both materials are at risk of exposure to the microbial contamination. To address this, antibiotics have been loaded onto membranes as drug-delivery systems, a strategy that has not yet been explored for PDO membranes. In this study, the oral polymicrobial contamination of PDO-based membranes was evaluated and compared with collagen membranes and aimed to develop an amoxicillin-loaded PDO (AMX-PDO) membrane. For this purpose, PDO membranes with different pore sizes (0.25, 0.50, and 1.00 mm) and two commercially available collagen membranes were evaluated, using in vitro and in situ models, in terms of polymicrobial accumulation. Next, AMX-PDO membranes were developed by glow discharge plasma using Ar and O<sub>2</sub> gases and an amoxicillin compound. The findings revealed similar microbial levels for both PDO and collagen-based membranes, but PDO membranes modulated microbial composition with reduced (∼3-5 fold-decrease) levels of specific oral pathogens. The AMX-PDO membrane maintained similar physical and chemical properties to those of untreated membranes, but it significantly reduced polymicrobial accumulation and prevented microbial cells from passing through them. Thus, they acted as more than passive physical barriers only, but rather as biologically active barriers.

Employing nanotechnology for drug delivery provides diverse nanosize particles ranging from one to a thousand nanometers. Reduced size improves drug bioavailability by increasing drug diffusion and decreasing the efflux rate. These nanocarriers offer an enormous scope for modification following the chemical and biological properties of both the drug and its disease. Moreover, these nanoformulations assist in targeting pharmaceutically active drug molecules to the desired site and have gained importance in recent years. Their modern use has revolutionized the antitumor action of many therapeutic agents. Higher drug loading efficiency, thermal stability, easy fabrication, low production cost, and large-scale industrial production draw attention to the application of nanotechnology as a better platform for the delivery of drug molecules. Furthermore, the interaction of nanocarrier technology-assisted agents lowers a drug's toxicity and therapeutic dosage, reduces drug tolerance, and enhances active drug concentration in neoplasm tissue, thus decreasing the concentration in healthy tissue. Nanotechnology-based medications are being widely explored and have depicted effective cancer management <i>in vivo</i> and <i>in vitro</i> systems, leading to many clinical trials with promising results. This review summarizes the innovative impact and application of different nanocarriers developed in recent years in cancer therapy. Subsequently, it also describes the essential findings and methodologies and their effects on cancer treatment. Compared with conventional therapy, nanomedicines can significantly improve the therapeutic effectiveness of antitumor drugs. Thus, the adverse effects associated with healthy tissues are decreased, and adverse effects are scaled back through enhanced permeability and retention effects.
