An ecofriendly and green method for the synthesis of silver and copper nanoparticles has developed using aqueous leaves extract of Cassia occidentalis. The formation of AgNPs and CuNPs was monitored by measuring the UV-Vis spectra. The morphology and crystalline phase of the metal nanoparticles were determined using transmission electron microscopy (TEM) and scanning electron microscopy (SEM) with X-ray energy dispersive spectrophotometer (EDX) and X-ray diffraction (XRD). The synthesized metal nanoparticles were generally found to be spherical and oval in shape. The AgNPs and CuNPs showed highly potent antibacterial activity against Escherichia coli and Salmonella typhi bacteria, respectively. The CuNPs showed higher radical scavenging activity than AgNPs. The AgNPs showed lower haemolysis (1.7%) exhibiting lesser toxicity as compared to CuNPs. The CuNPs have better catalytic ability for the reduction of 4-nitrophenol and 2-nitrophenol as compared to AgNPs.

“…mentioned that, while cell availability may not be affected by the presence of LDH nanoparticles, they may generated reactive oxygen species, causing oxidative stress and inflammation as a protective response of the cell. Biocompatibility of Mg 2 Al‐CO 3 mixed with bone cement was assessed using the cell hemolysis technique on blood cells . Formulation of bone cements with less than 1.5 % of Mg 2 Al‐CO 3 LDH was sufficient to improve biocompatibility of the nanocomposite, with a percentage of hemolysis lower than 1.3 % compared to 3.6 % for non‐formulated bone cement.…”

This review highlights the current research on the interactions between biological cells and Layered Double Hydroxides (LDH). The as-prepared biohybrid materials appear extremely attractive in diverse fields of application relating to health care, environment and energy production. We describe how thanks to the main features of biological cells and LDH layers, various strategies of assemblies can be carried out for constructing smart biofunctional materials. The interactions between the two components are described with a peculiar attention to the adsorption, biocompatibilization, LDH layer internalization, antifouling and antimicrobial properties. The most significant achievements including authors' results, involving biological cells and LDH assemblies in waste water treatment, bioremediation and bioenergy generation are specifically addressed.

“…Mg 3 Al-LDHs were synthesized by coprecipitation method. 37 First, Na 2 CO 3 solution was taken in five-neck flask and purged with N 2 gas for 5 min. Then solution of Mg (NO 3 ) 2 Á6H 2 O and Al (NO 3 ) 2 Á6H 2 O with molar ratio of 2:1 and NaOH solution was added drop wise under N 2 gas atmosphere maintaining pH 10-11 and was continuously stirred under reflux conditions.…”

In this work, to inquire the impact of layered double hydroxide (LDH) nanoclay on functionalized poly(vinyl chloride) (PVC) through solution intercalation method, four kinds of nanocomposites were prepared. Mg-AL LDH and the obtained functionalize PVC composites were characterized through FT-IR, UV-Vis spectroscopy, TEM, XRD, contact angle, DSC, and UTM. Obtained results revealed that the functionalized PVC uniformly dispersed in the layer of LDH nanoclay. It is revealed that partially intercalated and disordered structure formed in PVC/LDH, PVC-TS (thiosulfate)/LDH, and PVC-S (sulfate)/LDH nanocomposites, whereas fully exfoliated structures formed in the PVC-TU (thiourea)/LDH nanocomposites. Further, it has been observed that the ultimate tensile strength for all the polymer nanocomposites enhanced with increased in the LDH content. These nanocomposites further exhibited higher thermal stability by at least by 51 C higher than the pristine PVC. Along with these, further it has been found that the functionalized PVC/LDH nanocomposites are proved to be effective as thermal stabilizer for PVC processing.(OH) 2 ] (A n− x/n )ÁnH 2 O, where M 2+ and M 3+ can be any divalent and trivalent metal ions, respectively. In positively charged layers "x" is the metal ionic ratio, M 3+ /(M 2++ M 3+ )A n− in the interlamellar region, which can be any anion (organic or inorganic). "n" is the molar amount of water present in the same region. As such, it has hydrotalcite like arrangement and this system provides a lot of possibilities for intercalation a compound. 3,[6][7][8] Additional Supporting Information may be found in the online version of this article.
