The use of nanoparticles (NPs) has generated an alternative pest control. objective was to evaluate the insecticidal effect zinc oxide (ZnO NPs), titanium dioxide (TiO2 and their combination on Bactericera cockerelli (Hemiptera: Triozidae) second-stage nymphs under laboratory greenhouse conditions in tomato. research carried out with leaf immersion bioassay method a complete randomized design, by direct plant spraying block design; both designs, control without NPs added. Mortality recorded...
Abstract Antifungal activity of zinc oxide (ZnO) and ZnO nanoparticles (ZnO NPs) was evaluated on the control Fusarium oxysporum Schltdl. (Nectriaceae) under laboratory greenhouse conditions. In vitro evaluation, poisoned culture media prepared, an explant placed in centre solid medium. The experimental design completely randomized with 18 treatments. Mycelial growth conidia concentration were evaluated. Subsequently, three treatments (3,000, 1,500, 100 ppm) NPs chosen for their evaluation...
Type 2 diabetes (T2D) in developed countries have a prevalence of 11% with diabetic foot infections as the most common cause hospitalization and amputation. To achieve healing ulcer wounds, appropriate dressings are essential their effectiveness can be enhanced nanoparticles, nevertheless ideal combinations dressing composition nanodrugs require further testing humans. We calcium alginate ZnO nanoparticles (CAZnODs) for treatment ulcers human patients. test efficacy CAZnODs we designed...
Benefits of nanotechnology in agriculture include reduced fertilizer loss, improved seed germination rate and increased crops quality yield. The objective this research was to evaluate the effects zinc oxide nanoparticles (ZnO-NPs), at 1500 ppm, on tomato (Solanum lycopersicum L.) growth. ZnO-NPs were synthetized produce either spherical or hexagonal morphologies. In research, we also studied two application methods (foliar drench) nanoparticles’ (NPs) surface modification with maltodextrin....
The synthesis of copper nanoparticles was studied by wet chemical methods using sulfate pentahydrate (CuSO 4 ·5H 2 O) and nitrogen ligands allylamine (AAm) polyallylamine (PAAm) as stabilizers. results suggest that the use these leads to exclusive formation metallic (Cu‐NPs). partially crosslinked (PAAmc) (NPs) with low yields high coating content, while linear PAAm NPs content. composition particles determined XRD average particle diameters were Debye‐Scherrer equation. TGA analysis...
Novel composites have been prepared via the incorporation of zinc oxide nanoparticles (nZnO) into poly(acrylic acid ‐co‐ itaconic acid) (poly(AA IA)) hydrogel. The were characterized by means Fourier transform infrared spectroscopy (FT‐IR), swelling studies, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and electron microscopy (SEM). amount nZnO incorporated hydrogel was determined using atomic absorbance spectrometry. In addition, antibacterial performance...
In recent years, interest in nutrient and nanoscale biostimulant use agriculture to improve seed germination crop productivity has increased. Nanoparticle priming improved growth quality crops of agricultural value. The following study shows the effect on bell pepper RZ F1 (35-71) with zinc oxide nanoparticles (ZnO NPs) different morphology: spherical hexagonal. Bell seeds were primed ZnO NPs at doses, 50 100 mg L-1. was carried out two phases. first phase consisted an in-vitro a chamber...
The thyroglossal cyst is found in 7% of the population and incidental papillary thyroid carcinoma a rare entity with an incidence 1 to 2%. clinical presentation indistinguishable from benign lesion histopathological postoperative study defines diagnosis. Papillary carcinomas have favorable prognosis cervical or distant metastases are rare. There now consensus on indication total thyroidectomy, radioablation iodine and/or suppressive therapy levothyroxine after being removed surgically [1-3]...

Los tratamientos consistieron cinco dosis NPs ZnO: 50, 100, 150, 200 250 mg L-1. resultados indicaron que mayor fue para con L-1 ZnO incremento 53 t ha-1, relación al testigo, misma tendencia peso del fruto mostró valores 1.74 kg, 1.45 kg...
One of the important domestic insects that transmit many pathogens to environment is Periplaneta Americana . The control methods this insect are often ineffective and have caused resistance in these insects. purpose present study was investigate effects contact feeding lethality titanium nanoparticles on In study, different concentrations were prepared for oral treatments P
Wound healing is a complex process often hindered by microbial infections, particularly in severe wounds like diabetic ulcers and burns. Collagen-based hydrogels offer potential solutions but lack mechanical support antibacterial properties. This study explores the incorporation of silver nanoparticles (AgNPs) into Collagen-Polyethylene Glycol (PEG) crosslinked with polyurethane (PU) for enhanced wound healing. The hydrogels, labeled CPEG-Ag, revealed dense fibrillar structure resulting from...
The synthesis and surface modification of ZnO nanoparticles, achieved through a controlled precipitation reaction using NaOH as precipitating agent with 0.2 molar ratio were studied. was carried out chemical hydrolysis at 80°C for 6 h, in order to promote better adhesion between inorganic particles polymer matrix when they used composite materials. Both 3-aminopropyltrimethoxysilane (APTMS) difunctional alcohol spiroorthocarbonate (SOC DIOL) modifying agents 0.5:1 respect nanoparticles....
The production of glucose oxidase (GOX) and catalase (CAT) by submerged fermentation the free immobilized xerophytic fungus Aspergillus niger under equal conditions was compared. To immobilize fungal spores, entrapment in PVA/alginate beads treated with NaNO3/CaCl2 performed. yield immobilization a diameter less than 1mm to 100%. Fungus growth substrate consumption were evaluated both systems, demonstrating lag-period presence case first cycle use. enzyme reuse carried out. In these cases,...
Micronutrient nanoparticles (NPs) are currently an option for chemical fertilization and biostimulation in crops. However, there is little information on the phytotoxic or biostimulatory effects of NPs at low concentrations some elements, such as Zn. In this study, effect Zn oxide (ZnO) germination, growth variables, nutritional attributes lettuce (<i>Lactuca sativa</i> L.) was evaluated comparison to sulfate.
