MSNs offer targeted drug delivery, enhancing therapeutic effectiveness while minimizing adverse effects on healthy cells. Due to their unique characteristics, MSNs provide targeted drug delivery, maximizing therapeutic effectiveness with minimal adverse effects on healthy cells. The review thoroughly investigates the role of MSNs as potent drug carriers, noted for their high drug-loading capacity and controlled release, which significantly improves drug permeability and retention. Additionally, it discusses surface modification techniques that enable MSNs to target cancer cells precisely. The manuscript provides comprehensive insights into various MSN applications, including their role in cancer diagnosis, the design of advanced biosensors, and the development of both conventional and stimuli-responsive drug delivery platforms. Special focus is given to stimuli-triggered MSN systems, responsive to internal stimuli (e.g., pH, redox, enzyme) and external stimuli (e.g., temperature, magnetic field, light, ultrasound), highlighting the cutting-edge progress in MSN technology. Additionally, the review delves into the immunogenicity and biosafety aspects of MSNs, underscoring their potential for clinical translation. Besides summarizing the current state of MSN research in oncology, this review also illuminates the path for future advancements and clinical applications.","PeriodicalId":228,"journal":{"name":"Small","volume":"25 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clarifying the comprehensive influence of synchronous OER on the morphology and microstructure of the coating is important. In this work, the electrodeposition process of porous lead dioxide coating is regulated by the way of linear potential increase and realized the rapid preparation of high-performance porous lead dioxide coating within 40 s. The morphology and microstructure, electrical, and electrochemical properties are characterized, combined with theoretical calculation and orthogonal analysis, to investigate the regulatory mechanism of the rapid growth of the porous lead dioxide by the electric potential.

Consequently, there is an urgent need for new methods that can quickly degrade and sensitively detect these compounds.

In this study, a multifunctional luminescent nanozyme Eu@Ce/UiO-67 composed of Eu<sup>3+</sup> and a bimetallic organic framework Ce/UiO-67 is developed for the degradation and dual-mode detection of paraoxon. The doping of Ce<sup>4+</sup> results in the formation of more defective structures in Eu@Ce/UiO-67, which significantly enhances the phosphatase activity of Eu@Ce/UiO-67 and the degradation efficiency of paraoxon. The hydrolysis product 4-nitrophenol (4-NP) shows a distinct UV-vis absorption in the visible light region and can quench the fluorescence of Eu@Ce/UiO-67 by the effect of photo-induced electron transfer (PET), thus achieving dual-mode detection of paraoxon by colorimetric and fluorescent methods.

However, the achievable high density of artificial neurons having a capacitor for emulating the integrate function of biological neurons has a limit. Furthermore, a low-voltage operation (<1.0 V) is essential for connecting with modern complementary metal-oxide-semiconductor-field-effect-transistor-based (C-MOSFET—based) integrated circuits. Here, a capacitorless memristive-neural integrated chip (MnIC) based on the negative differential resistance of the electrochemical metallization cell designed using a 28-nm C-MOSFET process in a foundry is reported. The fabricated MnIC exhibits extremely low-voltage operation (<0.7 V) via the rupture dynamics of Ag filaments formed in the GeS<sub>2</sub> chalcogenide layer, with a nonlinear increase in the action potential in a manner similar to a human sensory system. Moreover, to construct a fully-structured spiking neural network (SNN), an oxygenated amorphous carbon-based (α-CO<sub>x</sub>-based) synaptic device having 32 multi-level conductance states is designed. The designed MnIC and α-CO<sub>x</sub>-based synaptic device demonstrate real-time unsupervised learning via a spike-timing-dependent plasticity learning rule with an SNN.

Here, a oleophilic garnet suspension electrolyte design is reported, using inorganic solid electrolyte modified by low-surface-energy 1H,1H,2H,2H-perfluorooctyl trichlorosilane (PFOTS), to address the dilemma of fast charging and high specific energy in LMBs. With the oleophilic suspension electrolytes, the ionic conductivity of carbonate electrolyte is increased by ≈20%. Importantly, Li<sup>+</sup> transference number is increased by ≈50% (reaching 0.57). Furthermore, the oleophilic suspension electrolyte regulates the solid electrolyte interphase (SEI), resulting in improved Coulombic efficiency (from 98.9% to 99.5%) and decreased Li/electrolyte interfacial impedance (from 263 to 86.5 Ω).

Reverse-selective H<sub>2</sub>/He separation membranes offer multiple advantages over conventional helium-selective membranes, which, however, suffer from low H<sub>2</sub>/He selectivity. To address this hurdle, a novel approach is proposed to tune the ultra-micropores of carbon molecular sieves (CMS) membranes through fluorination of the polymer precursor. By incorporating -CF<sub>3</sub> units into the backbone of Tröger's base polymers, the microporosity of CMS is tailored and reverse-selective H<sub>2</sub>/He CMS membranes are deployed with remarkable separation performance, surpassing most reported membranes. These CMS membranes exhibit a H<sub>2</sub> permeability of 1505.2 Barrer with a notable H<sub>2</sub>/He selectivity of 3.8. Barometric sorption tests reveal preferential sorption of H<sub>2</sub> over He in the fluorinated CMS membranes, which also demonstrate a significantly higher H<sub>2</sub>/He diffusion selectivity compared to unfluorinated samples. Material studio calculations indicate that the “slim” hydrogen molecule penetrates ultra-micropores more readily than the spherical He molecule, thus achieving reverse H<sub>2</sub>/He selectivity.
