The co-precipitation method was used to produce cadmium oxide nanoparticles (CdO NPs) with different plant extracts such as Tinospora Cardifolia (stems), Rhododendron arboretum (flower), Pichrorhiza Kurroa (roots), Nardostachys jatamansi (roots), Acorus Calamus (roots), Corylus Jacquemontii (seeds), and Emblica Officinalis (fruit). To extract organic matter from the as-prepared sample, it was calcined at a temperature ranging from 500-600⁰ C. X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), and Transmission electron microscopy (TEM) were used to investigate the structure and morphology of the calcined oxide nanoparticles. The CdO NPs were well amorphous particle form and had an average particle size of 20-55 nm. The cytotoxicity of the Pichrorhiza Kurroa shows strong antiproliferative activity against rat skeletal myoblast cell lines (L-6).

This research covers the bio preparation of cadmium oxide nanoparticles (CdO NPS) with the use of aqueous plant extracts from the Curcuma rhizome. Characterization of CdO NPs was performed using (XRD), UV-VIS spectroscopy, (FT-IR), (AFM), and (FE-SEM). The XRD technique has confirmed the crystallinity of CdO NPs with an average crystalline CdO NPs scale of 33,21nm. The optical bandgap of CdO NPs is 5.5 eV. The nanoparticle size of the particles is 571.32 nm as seen (FE-SEM) and the average diameter of CdO NPs is 70.41 nm as shown by AFM. CdO NPs is screened for antimicrobial activity against a variety of human pathogens, including Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, Escherichia coli, Candida albicans, and Trichophyton rubrum using agar well diffusion. The anticancer efficacy of CdO NPs against human colon cells (HT-29) was tested using an MTT assay. The results showed that CdO nanoparticles demonstrated superior antibacterial activity in the area of antimicrobial strain inhibition. CdO NPs have shown substantial anticancer.

Cadmium oxide (CdO) nanoparticles were synthesized for the first time via an eco-friendly, simple and cost effective green synthesis method mediated by corn husk extract. Indeed, the corn husk extract acted as an effective chelating agent in facilitating the formation of the CdO nanoparticles. XRD analysis confirmed the formation of highly crystalline face-centred cubic CdO nanoparticles. The structural morphology and the constituents of the resultant CdO nanoparticles were investigated by High Resolution-Scanning Electron Microscopy (HR-SEM) and Energy Dispersive X-rays Spectroscopy (EDS). Attenuated Total Reflection-Fourier Transformer Infrared spectroscopy (ATR-FTIR) and Raman spectroscopy measurements have been obtained to complete the structural investigation. UV-Visible spectroscopy analysis showed a wide absorbance spectral range of 250-2500 nm. Consequently, the CdO nanoparticle displayed photoluminescence emission peak at 508 nm.

The goal of this study is to prepare and characterize the green synthesis of CdO nanoparticles using Curcuma longa plant. Using X-Ray diffraction (XRD) analysis, UV-Visible spectroscopy and scanning electron microscope SEM analysis, the thorough characterization of CdO nanoparticles was carried out, demonstrating that the prepared CdO nanoparticles were polymorphic.

Green synthesis of CdO nanoparticles
CdO nanoparticles based on Andrographis paniculata plant extract were synthesizedby biological method and characterized by XRD, FESEM, HRTEM and FTIR. XRD exhibits face centred cubic structure with an average crystallite size of 22 nm and the lattice strain (W–H plot) is 0.0023. From the HRTEM, the particles are spherical. The vibrational stretching mode of Cd–O is 456 cm−1. From the UV–Vis spectra, the optical energy bandgap is estimated as 2.33 eV. The photoluminescence emission peaks at 360, 430, 486, 528 and 616 nm are observed for the excitation at 220 nm. The electrochemical study by cyclic voltammetry reveals the quasi reversible reduction and irreversible oxidation versus Saturated Calomel Electrode (SCE). The potential is referred to the Fc/Fc+ couple under the experimental conditions. The biosynthesized CdO nanoparticles are tested against gram positive (Rhodococcus rhodochrous and Staphylococcus aureus) and gram negative (Escherichia coli, Aeromonas hydrophila and Vibrio Cholera) bacterial strains. It is noted that the bioengineered CdO nanoparticles show a good antibacterial activity (zone of inhibition: E. coli-16 mm) bacteria.

The word 'Nano' received great attention of world, due to their fabulous and novel applications in numerous fields. Cadmium sulphide nanoparticles (CdS NPs) are unique in their properties due the size and shape, and are popular in the area of biosensor, bio-imaging, nano-medicine, molecular pathology, antimicrobial activities, photovoltaic cells, semiconductor, and drug delivery, etc. Due to its fascinating applications, it was synthesized using several methods and explored for its all possible applications. The most affordable, efficient, friendly and biocompatible way of creation of CdS NPs is biogenic synthesis using microorganisms such as bacteria, fungus, algae, enzymes, proteins and parts of plants. In biogenic synthesis of CdS, cadmium undergoes bio-reduction by the variety of natural products present in microorganism as well as in plants. In present review, inclusive study was piloted on the nano-synthesis, characterization and various applications of CdS NPs made using different plant sources and microorganism.

The absorbance spectra were used to estimate the values of optical band gap and particle size of CdS nanoparticles. A possible involved mechanism for the biosynthesis of CdS nanoparticles has also been proposed.
A facile green extracellular biosynthesis of CdS nanoparticles by immobilized fungus
Chemical Engineering Journal, 2009
A novel "green" route to prepare CdS nanoparticles under ambient conditions is reported. The long-term studies were carried out with immobilized fungus Coriolus versicolor in continuous column mode. The immobilized fungus served a dual purpose of both bioremediating cadmium as well as synthesizing stable CdS nanoparticles in aqueous conditions. The fungus immobilized in the column could remove 98% cadmium within 2 h. The continuous and extracelluar production of autocapped CdS nanoparticles is an added advantage of this system. Interestingly, no external source of sulfur is required for the transformation of toxic Cd to non-toxic CdS. The thiol group of the fungal protein was found mainly responsible for the production of such highly stable and autocapped CdS nanoparticles. The physico-chemical properties of the particles were studied by FTIR, XRD, SEM, TEM, AFM, TGA and PL.
