Their unique physicochemical features, including high surface-to-volume ratios, tunable surfaces, and the ability to cross biological barriers, enable applications in targeted drug delivery and theranostics. Gold (Au), silver (Ag), iron oxide (Fe₃O₄), zinc oxide (ZnO), and platinum (Pt) NPs demonstrate outstanding efficacy: AuNPs achieve &gt;90 % drug loading and 3–5× improved tumour targeting, AgNPs show up to 99 % antimicrobial activity, and Fe₃O₄ NPs function as both drug carriers and MRI contrast agents. However, toxicity remains a major hurdle. Reported challenges include dose-dependent cytotoxicity (IC₅₀: 10–40 μg/mL), hepatic retention (30–40 %), oxidative stress (2–10× ROS increase), and immune activation (up to 3-fold cytokine elevation). Safety is governed by physicochemical properties, with &lt;10 nm NPs showing efficient penetration but higher genotoxicity, and cationic surfaces being 2–3× more cytotoxic. Several strategies have been developed to overcome these barriers. PEGylation reduces macrophage uptake by 60–75 % and extends circulation time, biodegradable hybrids reduce long-term accumulation by 70–80 %, and controlled-release systems cut doses by 30–50 % without compromising efficacy.

For this purpose, chitosan (Cs) and polyvinyl alcohol (PVA) polymers were used to produce nanofibers with a 20/80 ratio by electrospinning, with capsaicin serving as the anticancer drug. The properties of the fabricated nanofibers were evaluated by field emission scanning electron microscopy. Also, gold nanoparticles were used to analyze and compare its effectiveness against the K562 cancer cell line. This cell line was prepared from Pasteur cell bank and cultured in DMEM medium. Subsequently, the anticancer effect of synthetic nanofibers in different concentrations was assessed by performing survival test, apoptosis by annexin and propidium iodide staining, and cell scratch assay. The electron microscopy study demonstrated the uniformity and purity of the nanofiber structure. The results showed that capsaicin, dose-dependently, reduced the viability of K562 cells after 72 h (<em>P</em> &lt; 0.01). The apoptotic assay also indicated that the induction of apoptosis significantly increased by PVA/Cs/Caps(2 %) and PVA/Cs/Au(5 %)/Caps(10 %) compounds in the studied cell line (<em>P</em> &lt; 0.0001). Furthermore, scratch assay at 24, 48, and 72 h demonstrated that the mentioned compounds possess anti-migration potential, particularly at 48 h.

By incorporating an albumin-binding domain (ABD) peptide and a DC-guiding peptide (DCpep) into our previous CVB3 exosome vaccine (Exo), the AD-Exo vaccine demonstrated superior immunogenicity. It efficiently bound to mouse serum albumin, amplified antigen enrichment in dLNs, and enhanced DC uptake and maturation.
