Over recent years, extracellular vesicles (EVs), commonly termed exosomes, have gained prominence for their potential as natural nanocarriers. It has now been recognized that plants also secrete EVs. Despite this discovery, knowledge about EV biogenesis in plant cell cultures remains limited. In our study, we isolated and meticulously characterized EVs from the callus culture of model plant,
The present study reports a green chemistry approach for the rapid and easy biological synthesis of silver (Ag), gold (Au), bimetallic Ag/Au nanoparticles using callus extract Lithospermum erythrorhizon as reducing capping agent. biosynthesized were characterized with ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD) analysis, transmission electron microscopy (TEM). Our results showed formation crystalline metal nanostructures both spherical non-spherical shape. Energy...
This work addresses the issues of male reproductive health caused by pathozoospermia, which leads to a decrease in number and motility sperm cells. In many cases, this pathology is associated with ox idative stress. Seaweed known increase cellular resistance, making selenium-enriched brown algae ( Saccharina japonica ) promising research object. paper, we report preclinical study into ef f icacy biologically active supplement obtained from using modeled pathospermia (oligo- asthenospermia)...
Bionanocomposites are formed through the electrostatic interactions of exfoliated clay nanoparticles initially dispersed in an aqueous solution with chitosan macromolecules that gradually charged course a progressive pH decrease by chemical acidulating agent to exclude phase separation.
This study delves into the novel utilization of Aristolochia manshuriensis cultured cells for extracellular silver nanoparticles (AgNPs) synthesis without need additional substances. The presence elemental has been verified using energy-dispersive X-ray spectroscopy, while distinct surface plasmon resonance peaks were revealed by UV-Vis spectra. Transmission and scanning electron microscopy indicated that AgNPs, ranging in size from 10 to 40 nm, exhibited a spherical morphology....
Prospective adjuvant anticancer therapy development includes the establishing of drug delivery systems based on biocompatible and biodegradable carriers. We have designed films nanoparticles (NPs) low-esterified pectin hydrogel using ionic gelation method. investigated morphology, nanomechanical properties, biocompatibility activity. Hydrogel are characterized by tunable viscoelastic properties surface nanoarchitectonics through concentration esterification degree (DE), expressed in variable...
Abstract Fibrillary cellulose and nanocellulose are widely applied as fillers for the improvement of mechanical properties, thermostability, biodegradability polymers. Here, an opposite concept is suggested which to use structure‐forming directing scaffold, whereas polymers serve its modification. Cellulose possesses excellent but they badly affected by water; strength drops sharply, cellulosic materials swell, become dimensionally unstable, susceptible fungal degradation. The deterioration...
Abstract Bionanocomposites in the self-organized regime are prepared when chitosan is gradually charged course of progressive change pH by hydrolyzing D -glucono- δ -lactone solutions nanoparticles bearing negative charges on their surface. This novel approach applicable to formation monolithic hydrogels and films. Here bionanocomposites with clay saponite sepiolite having various geometry oxidized multiwall carbon nanotubes considered. Structural organization films studied scanning...
Conventional chemotherapeutic approaches currently used for brain tumor treatment have low efficiency in targeted drug delivery and often non-target toxicity. Development of stable effective vehicles the most incurable diseases is one urgent biomedical challenges. We developed polymer nanoparticles (NPs) with improved temozolomide (TMZ) promising therapy, performing a rational design polyelectrolyte complexes oppositely charged polysaccharides cationic chitosan anionic pectin. The NPs’...
The extracellular matrix (ECM) of the central nervous system (CNS), characterized by low stiffness and predominance carbohydrates on protein components, mediates limited cell proliferation migration. Pectins are polysaccharides derived from plants could be very promising for a tunable hydrogel design that mimics neural ECM. Aiming to regulate gel structure viscoelastic properties, we elaborated 10 variants pectin-based hydrogels via tuning concentration polymer number free carboxyl groups...
Abstract The study is aimed at imparting dimensional stability and some functionalities to cellulosic aerogels. polysaccharide suffers from mechanical strength loss in wetted state that restricts its application. Improvement achieved by mean of microfibrillation fibers combining intense treatment with freeze-thawing. Addition the latter decreases number cycles. Aerogels prepared microfibrillated cellulose freeze-drying hold their solutions makes possible treating them chemically without...
The microstructure and crystallization of the glasses with composition (100-x-y)TeO2-xPbO·P2O5-yPbF2:zMF3 (M= Er, Eu, Nd; x=42.5-30, y=5-30, z=0.5-3.0) were investigated by transmission electron microscopy (TEM) luminescence methods. It was found that doping rare-earth (III) fluorides promoted nucleation in bulk glasses. sizes generated particles are about 2-5 nanometers their shapes close to spherical. growth rate crystallites depended on lead fluoride content glass forming rate. heat...
