Although metal–organic frameworks (MOFs) have been widely used in drug delivery, developing nanocarriers with both high stability and biocompatibility remains a significant challenge. This study developed a novel composite nano drug delivery system, PLGA-PDI@CP1@1, which combines poly(lactic-co-glycolic acid) (PLGA) and perylene diimide (PDI) with excellent fluorescence properties to effectively encapsulate MOF-based CP1. The system was further loaded with an active compound extracted from ginseng (compound 1) for the treatment of gliomas.

We present the results of a theoretical model for the cohesive energy, melting temperature and Debye temperature of silver (Ag) and gold (Au) nanoparticles, developed and analyzed using computer simulations in MATLAB, and validated against experimental data and other theoretical predictions. The results indicate that nanoparticles have lower cohesive energies because of the surface atoms that dominate, resulting in lower melting and Debye temperatures with decreasing particle size. The cohesive energy of Ag nanoparticles decreases from ~ 285 kJ/mol in the bulk to ~ 230 kJ/mol at 5 nm, accompanied by a corresponding decrease in the melting temperature from 1235 K to ~ 700 K, Debye temperature from 230 K to ~ 100 K. The cohesive energy of Au nanoparticles lowers from ~ 368 kJ/mol for bulk to ~ 300 kJ/mol for 5 nm, and the melting temperature and Debye temperature drop from 1337 and 415K, respectively, to around ~ 600K and ~ 200K simultaneously. The experimentally observed and theoretically predicted size dependent trends in these properties are consistent with these trends showing that these properties are intertwined by the atomic bonding strength and vibrational dynamics. All three properties are higher for Au due to stronger metallic bonding.

Commercial P fertilizers have low efficiency of delivery and utilization and are lost from plant root zones by either low availability or leaching or surface runoff that leads to environmental damage. This review investigates how nano P fertilizers (NPFs) can overcome the current inefficiencies of conventional formulations and, thus, enhance plant yield while minimizing negative environmental impacts. NPFs have significant potential for augmenting plant germination by more effectively penetrating seed coatings and facilitating greater water and nutrient uptake. The nanoscale nature of NPF also uniquely facilitates greater P absorption by roots, which in turn enhances chlorophyll synthesis, improves light absorption, and optimizes electron transport efficiency—key factors in boosting plant photosynthesis. Additionally, it stimulates overall physiological processes (e.g., secondary metabolite production, root exudation), increases antioxidant enzyme activities, and enhances plant yield. NPFs can also minimize the accumulation of toxic elements by several mechanisms, including controlling contaminant bioavailability in soil by enhancing competing plant essential element (e.g., P, Ca) uptake. Moreover, NPFs also mediate soil pH, which has important implications for soil biogeochemistry in low-pH agricultural areas. Soil microbiomes and associated processes will often improve with NPF application relative to conventional P formulations. Although great potential has been demonstrated, a mechanistic understanding of certain aspects of NPF activity remains incomplete, including impacts across diverse crop species, environmental conditions, and soil types. However, NPFs offer great potential as an important tool in the transformation of conventional agriculture, simultaneously lessening the usage of finite P resources, reducing the environmental footprint of agriculture, and improving future food security.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455622","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}
