These systems have been under development for decades to deduce safer, bioavailable, specific, selective and efficacious modalities. Nanotechnology based drug delivery systems proposed to solve these issues, have led to a boom in nanoparticle based, liposomal, nanovesicles, nanocapsules, and similar provisions. The improvement of the existing available systems inspired biodegradable nanostructures such as nanofibers, nanomesh and nanoflowers. These structures provide better opportunities to improve targetability, bioavailability, better safety profiles. The platforms additionally facilitate controlled release of the loaded drugs. This minireview explores nanofibers, nanomesh and nanoflowers in breast cancer treatment as emerging nanostructures for delivery of chemotherapeutics. Nanofibers emulate the natural extracellular matrix which can be modified for biodegradability and tumor identification. Nanomesh provide large drug-antigen loading platform with interwoven strands.On the other hand, nanoflowers can be conveniently modulated to control the release of the drug. These nanostructures offer innovative solutions to the typical drawbacks of drug absorption, selectivity and delivery on tumor sight. In this minireview, we aim to comprehensively present how these nanostructures are created, address their mechanism of action and how they are developing the landscape of breast cancer drug delivery systems.The study prioritizes these nanostructures over their conventional counterparts due to their visible benefits while also addressing their limitations which should be further researched upon, for breast cancer therapeutics.</div></div>","PeriodicalId":100959,"journal":{"name":"Next Nanotechnology","volume":"8 ","pages":"Article 100159"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143820588","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}

PD was thermally and chemically modified to PD-Activated Carbon (PDAC) and PDAC impregnated with Zinc Oxide Nanoparticles (PDAC-ZnO-NPs). The produced adsorbents (PDAC and PDAC-ZnO-NPs) were appropriately characterized. Batch adsorption experiment was designed by Definitive Screening Design (DSD) for parameters: adsorption temperature (25 – 50°C), contact time (10 – 60 min), agitation rate (50 – 250 rpm), and adsorbent dosage (50 – 250 mg). ZnO nanoparticle impregnation increased the surface area from 965 m²/g to 981 m²/g and enhanced the availability of oxygen-containing functional groups, thereby improving DBT affinity. The BET surface area increased from 965 m²/g to 981 m²/g after ZnO-NP impregnation, indicating enhanced adsorption capacity. The equilibrium data for DBT removal were fitted to isotherm, kinetic, and thermodynamic models, with model constants evaluated. The desulfurization process achieved an optimum DBT percentage removal (%DBTR) of 85.47 % with PDAC and 95.12 % with PDAC-ZnO-NPs. The desulfurization equilibrium data fitted the Freundlich isotherm, the Pseudo-Second-Order (PSO) kinetic model and, thermodynamic analysis indicated that DBT removal process was spontaneous and endothermic, with entropy (ΔS) and enthalpy (ΔH) changes of 140.12 J/mol·K and 40.25 kJ/mol for PDAC, and 110.49 J/mol·K and 30.01 kJ/mol for PDAC-ZnO-NPs respectively. The %DBTR decreased by 6.1 % for PDAC-ZnO-NPs after five regeneration cycles, demonstrating its reusability.

However, its bioinert nature limits osseointegration, affecting long-term implant stability.

The nanocomposites were evaluated through scratch testing, providing quantitative insights into their mechanical and wear resistance properties. The results demonstrated that fZnO significantly improved scratch resistance, reducing residual scratch depth by 34 % compared to cZnO-reinforced composites. Moreover, while the addition of HA did not compromise the reinforcing effect of fZnO, the cZnO-HA hybrid nanocomposite exhibited a 20 % lower coefficient of friction (COF), which could be problematic for implant stability due to potential loosening. In contrast, the fZnO-HA hybrid nanocomposite demonstrated superior scratch resistance, lower pile-up formation, and improved fixation, making it a particularly promising candidate for load-bearing orthopedic applications such as hip prosthesis stems.
