Background: This study explored the pharmacokinetics, tissue distribution, and excretion profile of zinc oxide (ZnO) nanoparticles with respect to their particle size in rats. Methods: Two ZnO different (20 nm 70 nm) were orally administered male female rats, respectively. The area under plasma concentration-time curve, excretion, fate organs analyzed. Results: concentration both sizes increased during 24 hours after administration a dose-dependent manner. They mainly distributed such as...
We present the mechanism for cellular uptake of layered double hydroxide (LDH) nanoparticles that are internalized into MNNG/HOS cells principally via clathrin-mediated endocytosis. The intracellular LDHs highly colocalized with not only typical endocytic proteins, such as clathrin heavy chain, dynamin, and eps15, but also transferrin, a marker process, suggesting their specific internalization pathway. loaded an anticancer drug (MTX−LDH) were prepared to confirm efficacy delivery systems....
In this feature article, the applications of layered nanomaterials as green materials are demonstrated along with their structures and properties. Due to unique 2-dimensional biocompatibility, various eco- bio-friendly can be hybridized nanoparticles such double hydroxides (LDHs), hydroxy salts (HDSs) cationic clays. From small molecules drugs, herbicides, fertilizers, food ingredients large substances like deoxyribonucelotides (DNA), protein, enzymes, functional incorporated into via...
Abstract The surface of layered double hydroxide nanoparticles, a potential drug‐delivery nanovehicle, is modified with the cancer‐cell‐specific ligand, folic acid. modification successfully accomplished through step‐by‐step coupling reactions aminopropyltriethoxysilane and 1‐ethyl‐3‐(3‐dimethyl aminopropyl)‐carbodiimide. In order to evaluate cancer‐cell targeting effect folic‐acid‐grafted utilizing fluorescence‐related assay, both without acid moiety are labeled fluorescein...
Abstract Layered double hydroxides (LDHs) are biocompatible materials which can be used as drug‐delivery nanovehicles. In order to define the optimum size of LDH nanoparticles for efficient cellular uptake and pathway, we prepared different sized with narrow distribution by modulating crystal growth rate, labelled each particle a fluorophore using silane coupling reaction. The rate LDHs was found highly dependent on (50>200≥100>350 nm), whose range 50 200 nm selectively internalized...
While development of a sodium-ion battery (SIB) cathode has been approached by various routes, research on compatible anodes for advanced SIB systems not sufficiently addressed. The anode materials based titanium oxide typically show low electrical performances in primarily due to their electrical/ionic conductivity. Thus, this work, layered oxides were hybridized with covalent organic nanosheets (CONs), which exhibited excellent conductivity, be used as SIBs. Moreover, enlarge the...
A CON are hybridized with layered SnS 2 to improve electrical conductivity and structural stability of for lithium ion battery systems. Therefore, the hybrid shows outstanding performances over 5600 charge/discharge cycles.

Study on can provide critical information about practical biological applications, finally contributing sustainable development...
A methotrexate (MTX)-layered double hydroxide (LDH) hybrid have been developed as a drug delivery system, in which an anticancer drug, MTX, was intercalated into 2-dimensional LDH nanovehicle to form nanohybrid. According the comparative cell viability studies between MTX only and its nanohybrid on sensitive resistant culture lines, it found that MTX-LDH could bypass resistance eventually inhibit cancer proliferation very effectively compared free due enhanced permeability retention effect...
