Abstract
Intravesical instillation is an effective post-treatment for bladder cancer performed by delivering medications directly into the bladder to target the remaining cancer cells. The current study thus aimed to develop porous poly(L-lactide-co-ε-caprolactone) (PLCL) microspheres encapsulated with 10-hydroxycamptothecin (HCPT) via microfluidics to serve as a drug delivery system with persistent floating capacity and sustained HCPT-release property for intravesical instillation. A microfluidic device was designed to fabricate PLCL microspheres and encapsulate HCPT (HCPT-MS) within them; methanol and tridecane were introduced into an oil phase as a co-solvent and pore-forming agent, respectively, to regulate the floating ability of microspheres. The physicochemical properties of the resulting microspheres were characterized, and the floating behavior, release profile and anti-tumor effects of HCPT-MS were investigated. The obtained spherical HCPT-MS were 119.23 μm in size, monodisperse, and featured a porous concave surface and hollow structure. The encapsulation efficiency and drug loading of HCPT within HCPT-MS was around 67% and 4.9%, respectively. HCPT-MS exhibited impressive floating capabilities in water, PBS and artificial urine even in a simulated bladder dynamic environment. These microspheres remained afloat after being subjected to 90 repeated simulated urination processes. The sustained release of HCPT from these floating microspheres lasted for more than 10 days. The IC50 (half maximal inhibitory concentration) of HCPT-MS was calculated to be 52.14 μg mL-1. T24 cells (human bladder cancer cells) when cultured with HCPT-MS at such a concentration were severely inhibited, and the inhibition further enhanced with an increase in culture time. Hence, the feasibility of the current porous and floating HCPT-MS as a formulation for intravesical instillation to deliver medications into the bladder with sustained release and stability was thus substantiated.

The Influence of Graphene Oxide-Fe 3O 4 Differently Conjugated with 10-Hydroxycampthotecin and a Rotating Magnetic Field on Adenocarcinoma Cells. Int J Mol Sci 2024; 25:930.

Abstract
Nanoparticles (e.g., graphene oxide, graphene oxide-Fe3O4 nanocomposite or hexagonal boron nitride) loaded with anti-cancer drugs and targeted at cancerous cells allowed researchers to determine the most effective in vitro conditions for anticancer treatment. For this reason, the main propose of the present study was to determine the effect of graphene oxide (GO) with iron oxide (Fe3O4) nanoparticles (GO-Fe3O4) covalently (c-GO-Fe3O4-HCPT) and non-covalently (nc-GO-Fe3O4-HCPT) conjugated with hydroxycamptothecin (HCPT) in the presence of a rotating magnetic field (RMF) on relative cell viability using the MCF-7 breast cancer cell line. The obtained GO-Fe3O4 nanocomposites demonstrated the uniform coverage of the graphene flakes with the nanospheres, with the thickness of the flakes estimated as ca. 1.2 nm. The XRD pattern of GO-Fe3O4 indicates that the crystal structure of the magnetite remained stable during the functionalization with HCPT that was confirmed with FTIR spectra. After 24 h, approx. 49% and 34% of the anti-cancer drug was released from nc-GO-Fe3O4-HCPT and c-GO-Fe3O4-HCPT, respectively. The stronger bonds in the c-GO-Fe3O4-HCPT resulted in a slower release of a smaller drug amount from the nanocomposite. The combined impact of the novel nanocomposites and a rotating magnetic field on MCF-7 cells was revealed and the efficiency of this novel approach has been confirmed. However, MCF-7 cells were more significantly affected by nc-GO-Fe3O4-HCPT. In the present study, it was found that the concentration of nc-GO-Fe3O4-HCPT and a RMF has the highest statistically significant influence on MCF-7 cell viability. The obtained novel nanocomposites and rotating magnetic field were found to affect the MCF-7 cells in a dose-dependent manner. The presented results may have potential clinical applications, but still, more in-depth analyses need to be performed.

Abstract
10-Hydroxycamptothecin (HCPT) is a natural plant alkaloid from Camptotheca that shows potent antitumor activity by targeting intracellular topoisomerase I. However, factors such as instability of the lactone ring and insolubility in water have limited the clinical application of this drug. In recent years, unprecedented advances in biomedical nanotechnology have facilitated the development of nano drug delivery systems. It has been found that nanomedicine can significantly improve the stability and water solubility of HCPT. NanoMedicines with different diagnostic and therapeutic functions have been developed to significantly improve the anticancer effect of HCPT. In this paper, we collected reports on HCPT nanomedicines against tumors in the past decade. Based on current research advances, we dissected the current status and limitations of HCPT nanomedicines development and looked forward to future research directions.

Trivalent Cations Detection of Magnetic-Sensitive Microcapsules by Controlled-Release Fluorescence Off-On Sensor. NANOMATERIALS 2021; 11:nano11071801.

Abstract
A pyrene-based derivative, 2-((pyrene-1-ylmethylene)amino)ethanol (PE) nanoparticle, was encapsulated via water-in-oil-in-water (W/O/W) double emulsion with the solvent evaporation method by one-pot reaction and utilized as a fluorescence turn-on sensor for detecting Fe3+, Cr3+, and Al3+ ions. Magnetic nanoparticles (MNPs) embedded in polycaprolactone (PCL) were used as the magnetic-sensitive polyelectrolyte microcapsule-triggered elements in the construction of the polymer matrix. The microcapsules were characterized by ultraviolet–visible (UV–Vis) and photoluminescence (PL) titrations, quantum yield (Φf) calculations, 1H nuclear magnetic resonance (NMR), scanning electron microscopy (SEM), and superconducting quantum interference device magnetometry (SQUID) studies. This novel responsive release of the microcapsule fluorescence of the turn-on sensor for detecting trivalent cations was due to the compound PE and the MNPs being incorporated well within the whole system, and an effective thermal and kinetic energy transfer between the core and shell structure efficiently occurred in the externally oscillating magnetic field. The magnetic-sensitive fluorescence turn-on microcapsules show potential for effective metal ion sensing in environmental monitoring and even biomedical applications. Under the optimal controlled-release probe fluorescence conditions with high-frequency magnetic field treatment, the limit of detection (LOD) reached 1.574–2.860 μM and recoveries ranged from 94.7–99.4% for those metals in tap water.

Abstract
Nano-drug delivery systems that integrate inorganic and organic or even bioactive components into a single nanoscale platform are playing a hugely important role in cancer treatment. In this article, the fabrication of a versatile nanocarrier based on self-assembled structures of gold nanoparticles (AuNPs)-zein is reported, which displays high drug-loading efficiency for needle-shaped hydroxycamptothecin (HCPT) nanocrystals. The surface modification with folate-conjugated polydopamine (PFA) renders them stable and also facilitates their selective cellular internalization and enhancement of endocytosis. The release of payloads from nanocomplexes (NCs) was shown to be limited at physiological pH (17.1±2.8%) but significantly elevated at endosomal/lysosomal pH (58.4±3.0%) and at enzymatic environment (81.4±4.2%). Compared to free HCPT and its non-targeting equivalent, HCPT@AuNPs-Zein-PFA exerted a superior tumor suppression capacity as well as low side effects due to its active and passive targeting delivery both in vitro and in vivo. These results suggest that the NCs with well-defined core@shell nanostructures encapsulated with HCPT nanocrystals hold great promise to improve cancer therapy with high efficiency in the clinic. STATEMENT OF SIGNIFICANCE A novel nanocomplex with HCPT nanocrystals encapsulated was designed to achieve selective cellular uptake by endocytosis, acid responsive release in the tumor microenvironment and excellent tumor suppression without toxicity. This nanocomplex with conjugation of folate was stable in the bloodstream, with minimal drug release in extracellular conditions, leading to prolonged blood circulation and high accumulation in tumor tissues. The entrapment of a nanocrystal drug into nanomaterials might be capable of delivering drugs in a predictable and controllable manner.

Abstract
Organic/inorganic nanohybrids, which integrate advantages of the biocompatibility of organic polymers and diversified functionalities of inorganic nanoparticles, have been extensively investigated in recent years. Herein, we report the construction of arginine-glycine-aspartic acid-cysteine (RGDC) tetrapeptide functionalized and 10-hydroxycamptothecin (HCPT)-encapsulated magnetic nanohybrids (RFHEMNs) for integrin αVβ3-targeted drug delivery. The obtained RFHEMNs were near-spherical in shape with a homogeneous size about 50 nm, and exhibited a superparamagnetic behavior. In vitro drug release study showed a sustained and pH-dependent release profile. Cell viability tests revealed that RFHEMNs displayed a significant enhancement of cytotoxicity against αVβ3-overexpressing A549 cells, as compared to free HCPT and nontargeting micelles. Flow cytometry analysis indicated that this cytotoxic effect was associated with dose-dependent S phase arrest. Finally, RFHEMNs exerted encouraging anti-cell-migration activity as determined by an in vitro wound-healing assay and a transwell assay. Overall, we envision that this tumor-targeting nanoscale drug delivery system may be of great application potential in chemotherapy of primary tumor and their metastases.

Abstract
Multifunctional mesoporous silica nanocomposites are attractive carriers for targeted drug delivery in nanomedicine. Although promising developments have been made in the fabrication of multifunctional mesoporous silica nanocomposites, the design and mass production of novel multifunctional carriers are still challenging. This paper reports the facile one-pot fabrication of a multifunctional inorganic composite composed of superparamagnetic Fe3O4 nanoparticles and coated dye-functionalized mesoporous silica with a high specific surface area. The resulting composite particles had a tunable particle size, special open pore channels with high specific surface area, which is quite favorable for drug loading and release properties, as well as luminescent and superparamagnetic properties suitable for targeted drug delivery and tracking. This composite exhibited low toxicity, suggesting potential biomedical applications.

Abstract
Assembly techniques are being intensely sought for preparing nanocomposites with tunable compositions and structures. Compared to other assembly techniques, the layer-by-layer (LBL) technique, which is based on the electrostatic attraction between oppositely charged species, provides a simple, versatile and powerful method to synthesize various types of one-dimensional (1D) hybrid nanostructures. In this review, we begin with the developments in the LBL synthesis of nanocomposites, with a focus on our recent results for synthesizing 1D hybrid nanostructures via LBL assembly. Compared to previous LBL processes, we conducted the in situ reaction on the surface of 1D nanostructures via electrostatic attraction between oppositely charged 1D nanostructures and ions in the solution in an attempt to produce 1D hybrid nanostructures. Moreover, these core-shell nanostructures can be transformed into nanotubes by the removal of the templates. The as-synthesized 1D hybrid nanostructures and nanotubes with tunable composition exhibited enhanced performance for various applications such as gas sensors, lithium-ion batteries and cellular imaging.
