Systemic toxicity induced by aggregated layered double hydroxide nanoparticles
Layered double hydroxide (LDH) nanoparticles are emerging as one of the promising nanomaterials for biomedical applications, but their systemic toxicity in vivo has received little attention. In the present study, the effects of inorganic nanoparticle aggregation on their systemic toxicity were examined. Remarkably, aggregation was observed after the mixing of naked LDH nanoparticles with salin...
متن کاملCorrosion Inhibitor Release from Zn-Al-[PO43-]-[CO32-] Layered Double Hydroxide Nanoparticles
Zn-Al layered double hydroxide (LDH) nanoparticles with carbonate as the charge balancing anion in the interlayer space were synthesized using co-precipitation method. Then, the carbonate base Zn-Al LDH nanoparticles were doped with phosphate ion via anion-exchange reaction to synthesize Zn-Al-[PO43-]-[CO32-]. The structure and composition were characterized by X-ray diffraction (XRD), Fourier ...
متن کاملHollow nanoshell of layered double hydroxide.
Hollow nanoshells of layered double hydroxide (LDH) have been fabricated using exfoliated LDH nanosheets as a shell building block and polystyrene beads as a sacrificial template.
متن کاملReduction in the size of layered double hydroxide nanoparticles enhances the efficiency of siRNA delivery.
Small interfering RNAs (siRNAs) are a potentially powerful new class of pharmaceutical drugs for many disease. However, the delivery of unprotected siRNAs is ineffective due to their susceptibility to degradation by ubiquitous nucleases under physiological conditions. Layered double hydroxide nanoparticles (LDHs) have been found to be efficient carriers of anionic drugs and nucleic acids. Our p...
متن کاملLayered double hydroxide nanoparticles as cellular delivery vectors of supercoiled plasmid DNA
We prepared stable homogeneous suspensions with layered double hydroxide (LDH) nanoparticles for in vitro gene delivery tests. The viability of HEK 293T cells in the presence of LDH nanoparticles at different concentrations was investigated. This revealed 50% cell viability at 500 microg/mL of LDH nanoparticles that is much higher than 50-100 microg/mL used for the delivery tests. The supercoil...
