While no nanoparticle-based drug delivery systems (NDDSs) are yet approved for use for targeting the central nervous system, this review critically analyses the development of NDDSs for the improvement of currently approved therapeutics for the symptomatic treatment of AD and PD. It showcases how NDDSs can help therapeutic payloads overcome existing limitations, such as insufficient drug accumulation in the brain and limited effectiveness, by enhancing their pharmacokinetics, bioavailability, brain penetration and accumulation, and overall therapeutic efficacy through drug encapsulation, manipulation of nanoparticle properties, and nanoparticle surface functionalisation. However, we also draw attention to widespread issues in the field that impede progress, including the poor selection of <i>in vitro</i> models and the inadequate design of pre-clinical <i>in vivo</i> studies.

The commonly used copper (Cu) CC is unsatisfactory because of its poor lithiophilicity. Here, we consider Zn doping on the Cu CC surface (Zn−Cu) and explore the reductive stability of a high-concentration electrolyte (HCE), consisting of 3.6 M Lithium Hexafluorophosphate (LiPF<sub>6</sub>) salt in a mixture of ethylene carbonate (EC) and diethylcarbonate (DEC), on the Zn−Cu (111) surface (HCE|Zn−Cu) using density functional theory (DFT) and ab initio molecular dynamics (AIMD) simulations. The interfacial reactions in the HCE|Zn−Cu system are compared to those on the pristine Cu (111) surface (HCE|Cu). We have also studied the effect of electron-rich environments on the decomposition mechanism of the HCE mixture on both the CC surfaces. It is found that the HCE mixture is electrochemically stable on both Cu and Zn−Cu surfaces in a neutral environment. However, under electron-rich conditions, only one DEC molecule has decomposed upon contact with the Cu CC surface, while the two PF<sub>6</sub><sup>−</sup> anion groups from Li salts have decomposed much faster (within 100 fs) when the HCE mixture interacts with the Zn−Cu surface. Our results indicate that Zn doping suppresses undesirable solvent decomposition and improves the quality of the solid electrolyte interphase (SEI) layer.</p>","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"10 12","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Isothermal experiments reveal that the highly soluble AAs valine, proline, and lysine form extensive multilayers on the nanoparticle surface, and infrared measurements indicate intermolecular interactions, particularly with valine and lysine, for higher AA contents. Conversely, the low solubility of tyrosine and glutamic acid restricts their adsorption capacity, despite their higher partitioning on the solid surface. Parameters derived from fitting a classic saturation model seem to align with well-documented physicochemical properties such as the hydrophobicity and the complexity indices – a promising first step towards formulating design principles. Scaling these parameters by the AA solubility reveals a clear correlation with the adsorption behavior.

It is widely acknowledged that the oxidation of Sn<sup>2+</sup> to Sn<sup>4+</sup> results in severe P-type doping, leading to increased recombination, which is a primary factor contributing to the lower device performance. In this perspective article, we summarized the utilization of metallic Sn in Sn-based PSCs to facilitate the reduction of Sn<sup>4+</sup> back to Sn<sup>2+</sup>.
