Abstract Preclinical studies have demonstrated that nanoparticles (NPs) hold significant potential for advancing cancer therapy by enhancing therapeutic efficacy while reducing side effects. Their effectiveness in solid tumors is, however, often constrained insufficient accumulation and penetration. Understanding how the physicochemical properties of NPs – such as size, shape, surface charge influence their interaction with cells within tumor is critical optimizing NP design. In this study, we addressed challenge inconsistent behavior systematically evaluating uptake both 2D 3D models, penetration spheroids. Our results showed larger exhibited higher internalization rates models but limited Furthermore, negatively charged consistently achieved superior deeper than neutral positively NPs. Spherical outperformed rod-shaped These findings underscore importance carefully tailoring to complex microenvironment improved outcomes real tumors.

Mathematical models are crucial for predicting the behavior of drug conjugate nanoparticles and optimizing delivery systems in cancer therapy. These simulate interactions among nanoparticle properties, tumor characteristics, physiological conditions, including resistance targeting specificity. However, they often rely on assumptions that may not accurately reflect vivo conditions. In vitro studies, while useful, fully capture complexities environment, leading to an overestimation nanoparticle-based therapy effectiveness. Advancements mathematical modeling, supported by preclinical data artificial intelligence, vital refining therapies improving their translation into effective clinical treatments.

Photothermal therapy (PTT) utilizes photothermal agents (PTAs) to generate heat at the local tumor site that leads ablation upon photoirradiation a specific wavelength of light. Currently, most available PTAs have weak selectivity and depositing ability, which poor therapeutic outcomes. PEGylation improves outcomes, prolongs systemic circulation time, enhances accumulation, reduces risk clearance by immune system. This paper reviews recent developments PEGylated in cancer from 2019 2023, highlighting their antitumour efficacy response post-therapy with agents, current challenges strategies. review aims foster knowledge dissemination on application nanomedicine an immunological perspective encourage clinical translation these nanomaterials.

This review aims to address the significant challenges of treating central nervous system (CNS) disorders such as neurodegenerative diseases, strokes, spinal cord injuries, and brain tumors. These are difficult manage due complexity disease mechanisms protective blood–brain barrier (BBB), which restricts drug delivery. Recent advancements in nanoparticle (NP) technologies offer promising solutions, with potential applications delivery, neuroprotection, neuroregeneration. By examining current research, we explore how NPs can cross BBB, deliver medications directly targeted CNS regions, enhance both diagnostics treatment. Key NP strategies, passive targeting, receptor-mediated transport, stimuli-responsive systems, demonstrate encouraging results. Studies show that may improve minimize side effects, increase therapeutic effectiveness models Alzheimer’s, Parkinson’s, stroke, glioblastoma. thus represent a approach for disorder management, combining delivery diagnostic capabilities enable more precise effective treatments could significantly benefit patient outcomes.
