Review on Green Synthesized Nanocomposites and Their Biological Activities

Abstract

In this paper, we reviewed the present status of synthesis of nano structured materials for technological development as bimetallic, trimetallic and various organic, inorganic polymers nanocomposites in the field of nanosciences. Nanocomposites play an important role in the field of sciences, engineering and industries due to their high catalytic power, high optical, electrical and mechanical properties, which can be very useful in the field of biosensors, nano medicines and many more as social welfare factor. There are many techniques used for the preparation of nanocomposites. Among them, green method is commonly used technique for the synthesis of nanomaterials which is cost-effective, eco-friendly and less hazardous materials for the environment. Here we attempt to present an elaborate work done in the field of nanocomposites dwelling upon their advantages, challenges and future prospects.

Novel Copper-Zinc-Manganese Ternary Metal Oxide Nanocomposite as Heterogeneous Catalyst for Glucose Sensor and Antibacterial Activity

“…Nanocomposites, especially heterocyclic ones, are considered advantageous over metallic nanoparticles as they play the role of a junction between two or more nanoparticles due to their high versatility. They have a promising position in medicinal chemistry owing to their wide spectrum of activities [ 24 ], including photosensitizer (e.g., Ag/Ti/Zn Trimetallic Nanoparticles and Carbon Quantum Dots Nanocomposites) [ 25 ], antimicrobial [ 26 ], and antioxidant activity (e.g., bio-Ag/CdO/ZnO@MWCNTs nanocomposites) [ 27 ], by using several different methods. For antibacterial activities, zinc- and copper-doped TiO 2 nanoparticles have been reported.…”

Native plants from the genus Vaccinium in Colombia and their potential uses. A review

“…Ripe V. floribudum fruits possess properties of interest for different industries, such as for the synthesis of photocatalytic nanocomposite materials (Vizuete et al, 2016). Anthocyanin molecules in fruits of V. floribundum and other Vaccinium species have hydroxyl groups that effectively bind with TiO 2 nanoparticles, which are important for the nanoparticle industry (Taco-Ugsha et al, 2020;Ringwal et al, 2021).…”

“…suspensions were removed from the reactor, centrifuged at 10min intervals, and their distinctive absorption spectra were recorded using de-ionized water as a reference on a UV-vis spectrophotometer [25][26][27][28][29][30]33] . The concentrations of the dyes were calculated using calibration curves.…”

“…To confirmation of AgNPs formation, EDAX was performed, in which a strong peak of elemental Ag (69.14 weight %) and other peaks of O (22.24 weight %) and C (8.62 weight %) elements were present. The synthesized powdered sample of nano material additionally used for TEM analysis in which it was observed that the green AgNPs were polydispersed, smooth morphology and irregular shaped grains having average size of 43.75nm [12,[18][19][31][32][33][34][35][36] . BET isotherm plot (see Figure .2) of synthesized sample revealed that the synthesized AgNPs have single point surface area (SPSA at P/Po) was 0.1398 m 2 /gm, BET surface area was 0.1057 m 2 /gm, Langmuir surface area (LSA) was 0.1465m 2 /gm, and the micro pore area was 0.7834 m 2 /gm [28] , on the basis of observed data due to which it may become a corrosion free material and may use as a good anti-corrosion material as well as protecting material.…”

“…Antioxidant activity of synthesized nano materials had been performed by DPPH method with respect to ascorbic acid as Figureure-3), which is just near to the IC50 value of the standard ascorbic acid (i.e. 37.63μg/mL) [20][21][22][23][24]32,34] .…”
