Article
Full-text available
Toys have been used increasingly as an aid in the treatment of hospitalized children since the 1950s due to their positive effect on child psychology. Play dough plays a role in children's reflection of their imagination and development of hand skills. In addition to the educational properties of play dough, its chemical and biological safety is al...

Nature contains technologies that will make our lives easier. Hundreds of examples of biomimetics are now found in our daily life, one of such is biosensors. Biosensors studies have been continuously developing in recent years. The increase and widespread use of these studies are due to the fact that biosensors give correct results in many applicat...

Edible coatings act as a protective layer surrounding fruits and vegetables, extending their shelf life. The impact of sodium alginate (SA) 1% and chitosan (CH) 0.5% layering supplemented with nano zinc oxide (ZnO) (0.50 g/L) on orange quality was investigated for 20 days at 4 °C in this study. For the test samples of oranges, the effects of coatin...
Article
Full-text available
Plastic pollution is increasing day by day and the search for new, environmentally friendly products continues. Herein, for the first time, different degrees of mucilage were obtained from chia seeds and the film-forming behavior of levan biopolymer with these mucilages was investigated. Glycerol and sorbitol were used as plasticizers in the film d...
Article
Full-text available
Zinc oxide nanoparticles (ZnO NPs) were synthesized by Carica papaya leaf extract. The nanoparticles were characterized by UV–Vis spectrum, Fourier Transform Infrared spectroscopy (FTIR), X-ray Diffraction (XRD), Dynamic light scattering (DLS) analyser and Energy-dispersive X-ray spectroscopy analysis with a scanning electron microscope (SEM–EDX)....
Article
Full-text available
While the COVID-19 outbreak in India continues, a fatal fungal illness known as "Mucormycosis," often known as "Black Fungus," has caused a new health concern in the country. Several state governments proclaimed a pandemic after more than 11,000 instances of black fungus infection were confirmed across India. During the second wave of Coronavirus,...

Here, edible films were prepared by using levan biopolymer and different proportions of powdered ostrich eggshell. These films were characterized, and their bioactivity was measured. Adding ostrich eggshells to the levan films made the film surface smoother. Ostrich eggshell added to the films reduced the water vapor permeability in the films. Leva...
Article

Rhizome extract of Bergenia ciliata was used as a bio-functional reducing material for the green synthesis of copper oxide nanoparticles (CuO NPs). CuO NPs were characterized using ultraviolet–visible spectroscopy, Fourier transforms infrared spectroscopy, X-ray diffraction (XRD), dynamic light scattering, scanning electron microscopy (SEM) and ene...
Chapter
Scaffolds and other functional structures along with unique surface chemistry, morphology and interconnectedness to facilitate cell multiplication and adherence is a vital component of Tissue engineering (TE). Not only for cell movement but also for waste molecule excretion and adequate nutrient needs, these are considered to be a necessity. While...
Article
Full-text available
Nowadays, environmentally friendly, economical and efficient production of nanoparticles is increasingly important. The most appropriate nanoparticle synthesis that can be used in this process is green synthesis performed with biological materials (bacteria, fungi or plant). Metallic nanoparticles can be used in many applications and several studie...
Article
Full-text available
Paenibacillus polymyxa is a microorganism used for the production of carbohydrate biopolymer levan in this work. Film samples were prepared with different contents of levan/bentonite. Film samples were evaluated for thickness, water vapor permeability, tensile strength and elongation properties. The most suitable film composite was chosen to evalua...
Article
Full-text available
The synthesis of metal and semiconductor nanoparticles is an expanding research area due to the potential applications in the development of novel technologies. In this work reports novel biosynthesis of zinc oxide NPs by rhizome extract of plant B. ciliata. The biosynthesized zinc oxide NPs were characterized various techniques using UV–Vis, FTIR,...
Article
Full-text available
A simple, yet effective and rapid approach for the synthesis of titanium dioxide nanoparticles (TiO2 NPs) using Streptomyces sp. HC1 was developed. The in vitro activity of TiO2 NPs was demonstrated against human pathogenic bacteria and fungi. The synthesized nanoparticles were characterized using various methods and instruments, such as Zetasizer,...
Article
Among other polysaccharides, levan is a fructan with great potential in biotechnological applications due to its functional properties. The levan has only been available in small quantities because of its high cost. Here, a levan-producing microorganism was isolated from soil and identified as Pseudomonas mandelii. TGA, SEM, FTIR, ¹H NMR, ¹³C NMR a...
Article
The biopolymer of levan was produced with a density of 42.6 g/L by Pseudomonas mandelii in an optimized medium. The produced levan was characterized using FTIR, ¹H NMR, and ¹³C NMR spectroscopy techniques and Zetasizer. More robust films were obtained with glycerol used as plasticizer in levan/sodium bentonite clay films. Film samples were evaluate...
Article
Conductive polymers take much interest because of their electroactive definition as new generation smart biomaterials beside of their potential usage in proton exchange membrane fuel cells. Partially sulfonated styrene-(ethylene-butylene)-styrene (sSEBS) triblock copolymer based films (coded SEBS68 with the content of 68% SEBS, 5% PP, 26,5% Wax and...
Poster
Biological methods can be used to synthesize zirconia NPs without the use of any harsh, toxic and expensive chemical substances. The aim of this work is to produce zirconia nanoparticles by microorganism which isolated from soil.
Article
Some novel nanocomposites, which contain different concentrations of TiO2 nanopowders, were firstly prepared by using marble dust with convenient chemical components. Their nano structures characterized and distributions of the nano-aggregations related with internal structural content of the samples have been determined by X-ray Scattering Methods...
