Mesoporous silica nanoparticles (MSNs) are exceptionally promising drug carriers for controlled drug delivery systems because their morphology, pore structure, pore volume and pore size can be well tailored to obtain certain drug release profiles. Moreover, they possess the ability to specifically transport and deliver anti-cancer drugs when targeting molecules are properly grafted onto their surface. MSNs based drug delivery systems have the potential to revolutionize cancer therapy. This review provides a comprehensive overview of the fabrication, modification of MSNs and their applications in tumour-targeted delivery. In addition, the characterization and analysis of MSNs with computer aided strategies were described. The existing issues and future prospective concerning the applications of MSNs as drug carriers for controlled drug delivery systems were discussed.

Since decades after temozolomide was approved, no effective drugs have been developed. Undoubtedly, blood-brain barrier (BBB) penetration is a severe issue that should be overcome in glioblastoma multiforme (GBM) drug development. In this research, we were inspired by linezolid through structural modification with several bioactive moieties to achieve the desired brain delivery.

Extracellular vesicles (EVs) have been demonstrated to own the advantages in evading phagocytosis, crossing biological barriers, and possessing excellent biocompatibility and intrinsic stability. Based on these characteristics, EVs have been used as effective therapeutic carriers for drug delivery, but the low drug loading capacity greatly limits further applications. Herein, we developed a drug loading method based on cell-penetrating peptide (CPP) to enhance the encapsulation of therapeutic reagents in EVs, and EVs-based drug delivery system achieved higher killing efficacy to tumor cells.

The development of novel therapeutic strategies enabling the selective destruction of tumors while sparing healthy tissues is of great interest to improve the efficacy of cancer chemotherapy. In this context, we designed a β-glucuronidase-responsive albumin-binding prodrug programmed to release a potent Isocombretastatin A-4 analog within the tumor microenvironment. When injected at a non-toxic dose in mice bearing orthotopic triple-negative mammary tumors, this prodrug produced a significant anticancer activity, therefore offering a valuable alternative to the systemic administration of the parent drug.

Gemcitabine (GEM) is a first line chemotherapy drug for bladder cancer (BCa). GEM's lack of specificity has led to disadvantages, resulting in low efficiency, especially when combined with the targeted treatment of BCa stem cells (CSCs), which is considered the cause of BCa recurrence and progression. To enhance the anti-cancer effect and reduce the side effects of GEM targeting of BCa cells/CSCs, an aptamer drug conjugate (ApDC) targeted delivery system was used to improve the efficiency of GEM in BCa therapy using EpCAM aptamer-GEM conjugates based on the epithelial cell adhesion molecule (EpCAM), which is highly expressed on the cell membrane of BCa cells/CSCs.

This study examines heat transfer and nanofluid-enhanced blood flow behaviour in stenotic arteries under inflammatory conditions, addressing critical challenges in cardiovascular health. The blood, treated as a Newtonian fluid, is augmented with gold nanoparticles to improve thermal conductivity and support drug delivery applications. A hybrid methodology combining finite element method (FEM) for numerical modelling and artificial neural networks (ANN) for stability prediction provides a robust analytical framework.
