“…The MIC of AMOX-LZH against S. aureus was the best effect of the strains(0.12 mg ml À1 ). The confirmed results of MIC are lower than those obtained, [32] and antimicrobial activity of nanocomposite may be influenced by Zn C2 ion, particle size. Zinc has an excellent antibacterial activity against enteric bacterial pathogens common.…”

The intercalation of amoxicillin trihydrate (AMOX) into layered zinc hydroxide (LZH) has been achieved via ion-exchange method. The resulted nanocomposite (AMOX-LZH) has been thoroughly characterised by a number of techniques including powder X-ray diffraction (PXRD), FT-IR spectroscopy, TGA/DTG analysis and scanning electron microscopy (SEM). The PXRD results showed that the gallery height of LZH was expanded from 9.57 to 11.97 A , indicating that the AMOX anions were successfully intercalated into the interlayer space of LZHs. The increased thermal stability of nanocomposite was confirmed by TGA/ DTG analyses. Improved antibacterial activity and minimum inhibitory concentration of AMOX-LZH nanocomposite was evaluated against Grampositive bacteria Staphylococcus aureus, Klebsiella pneumonia and Gram-negative Escherichia coli using the disk diffusion technique. The sustained release of amoxicillin drug from the AMOX-LZH nanocomposite was also verified.

“…[37][38][39] In the first method, salt is used as the starting material, which is dissolved in aqueous solution and its pH is increased by the slow addition of basic solutions, such as sodium hydroxides, aqueous solution of ammonia, or aqueous carbonate, until precipitation occurs. 40 This method is very much similar to the coprecipitation method used in LDH preparation, where aqueous salt solutions are coprecipitated with counteranions of interest. 23,24 Metal layered hydroxides can also be prepared using metal oxide as the starting material.…”

Hydrotalcite-like compounds are two-dimensional inorganic nanolayers also known as clay minerals or anionic clays or layered double hydroxides/layered hydroxy salts, and have emerged as a single type of material with numerous biomedical applications, such as drug delivery, gene delivery, cosmetics, and biosensing. Inorganic nanolayers are promising materials due to their fascinating properties, such as ease of preparation, ability to intercalate different type of anions (inorganic, organic, biomolecules, and even genes), high thermal stability, delivery of intercalated anions in a sustained manner, high biocompatibility, and easy biodegradation. Inorganic nanolayers have been the focus for researchers over the last decade, resulting in widening application horizons, especially in the field of biomedical science. These nanolayers have been widely applied in drug and gene delivery. They have also been applied in biosensing technology, and most recently in bioimaging science. The suitability of inorganic nanolayers for application in drug delivery, gene delivery, biosensing technology, and bioimaging science makes them ideal materials to be applied for theranostic purposes. In this paper, we review the structure, methods of preparation, and latest advances made by inorganic nanolayers in such biomedical applications as drug delivery, gene delivery, biosensing, and bioimaging.

“…It is worth noting that the general trend in the decomposition temperatures of metal nitrates correlates well with the charge densities of the cations. 10 According to the results of Yuvaraj et al, the decomposition temperature is expected to decrease as the strength of the bond decreases.…”

“…For this reason, the decomposition temperature (290 o C) of (Ni, Ni)-HDS is higher than that of (Cu, Cu)-HDS. 10 In the case of mixed metal HDS systems, thermal decomposition studies are very important for understanding the role of the mixing effect on the nature of the N-O bond in M-O-NO 2 . Surprisingly, the decomposition temperature of (Cu, Ni)-HDS is very close to that of (Ni, Ni)-HDS, even though only 25% of the total number of sites for metal ions in (Cu, Ni)-HDS are occupied by nickel ions.…”

Layered mixed metal hydroxy double salts (HDS) with the formulas (Cu 0.75 Ni 0.25 ) 2 (OH) 3 NO 3 ((Cu, Ni)-HDS) and Cu 2 (OH) 3 NO 3 ((Cu, Cu)-HDS) were prepared via slow hydrolysis reactions of CuO with Ni(NO 3 ) 2 and Cu(NO 3 ) 2 , respectively. The crystal structures, morphologies, bonding natures, and magnetic properties of (Cu, Ni)-HDS and (Cu, Cu)-HDS were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transformation infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and a superconducting quantum interference device (SQUID). Even though (Cu, Ni)-HDS has a similar layered structure to that of (Cu, Cu)-HDS, the bonding nature of (Cu, Ni)-HDS is slightly different from that of (Cu, Cu)-HDS. Therefore, the magnetic properties of (Cu, Ni)-HDS are significantly different from those of (Cu, Cu)-HDS. The origin of the abnormal magnetic properties of (Cu, Ni)-HDS can be explained in terms of the bonding natures of the interlayer and intralayer structures.
