Abstract Despite significant advancements in cancer treatment, current therapies often fail to completely eradicate malignant cells. This shortfall underscores the urgent need explore alternative approaches such as vaccines. Leveraging immune system's natural ability target and kill cells holds great therapeutic potential. However, development of vaccines is hindered by several challenges, including low stability, inadequate response activation, immunosuppressive tumor microenvironment, which limit their efficacy. Recent progress various fields, click chemistry, nanotechnology, exosome engineering, neoantigen design, offer innovative solutions these challenges. These achievements have led emergence smart vaccine platforms (SVPs), integrate protective carriers for messenger ribonucleic acid (mRNA) with functionalization strategies optimize targeted delivery. Click chemistry further enhances SVP performance improving encapsulation mRNA antigens facilitating precise delivery review highlights latest developments technologies therapy, exploring both opportunities challenges advancing transformative approaches.

Abstract The development of biodegradable nanoparticles (NPs) for delivering anticancer drugs, such as letrozole (LTZ), offers a targeted approach cancer therapy. In this study, we synthesized poly(ε‐caprolactone)‐ co ‐poly(ethylene glycol) (PCL‐ ‐PEG) and fabricated LTZ‐loaded PCL‐ ‐PEG NPs (LTZ‐NPs) via emulsion‐solvent evaporation. Folic acid (FA), folate receptor‐targeting molecule, was conjugated to the (LTZ‐FNPs) enhance treatment efficacy against hormone receptor‐positive breast cells. Both FNPs exhibited spherical morphology (60–90 nm), with showing higher drug entrapment efficiency controlled release. LTZ release minimal at physiological pH but increased in acidic, cancer‐like environments, following Korsmeyer‐Peppas model, indicating combination Fickian non‐Fickian diffusion. cytotoxicity assays, LTZ‐FNPs toxicity MCF‐7 cells than LTZ‐NPs. Controlled altered gene expression, reducing B‐cell leukemia/lymphoma 2 protein (Bcl2) increasing caspase 8 (Casp8), promoting apoptosis. A shift SubG1 phase further confirmed enhanced LTZ‐FNP‐mediated cell death. Furthermore, p53 expression increased, while matrix metalloproteinase 9 (MMP‐9) decreased, inhibiting invasion. This study introduces system FA‐functionalized, pH‐sensitive delivery LTZ. holds great potential selective, efficient minimizing systemic
