The use of fluoride one the most effective ways to prevent tooth decay. </P><P> Objective: purpose this research was investigate effectiveness entrapped in chitosan nanoparticles vivo. Methods: Sodium loaded via ionic gelation tripolyphosphate nanoparticles. Characterization investigated by using zeta potential, size particles, loading capacities, encapsulation efficiency, and Fourier Transforms Infrared...
Polylactide-co-glycolide acid (PLGA) is known as a biodegradable and biocompatible polymer. This polymer has been highly used in tissue engineering. In this study, the biological behavior of Schwann cells (Rat) was investigated co-culture with L lysine/gelatine coated PLGA nano-fiber. dissolved hexafluoro propanol based solvent nanofiber prepared by an electronic method. They were gelatin poly-L-lysine individually. These properties Scanning Electron Microscopy (SEM) analysis contact angle...
The widespread use of nano-aptasensors is seen in various clinical areas, drug discovery, the development human health, and biological research. Variety design practices, detection strategies, areas application remind us need for review, comparison, classification this type sensors. aptasensors attractiveness using nanotechnology, like a wonderland, have attracted researchers' attention. Furthermore, these tools (rapid detection, quality control, level assessment paraclinical settings) are...
1, 3, 5-Tris (2-hydroxyethyl) isocyanurate functionalized SBA-15 is used as a novel, highly efficient, and recyclable heterogeneous nano-catalyst for the one-pot 3-component synthesis of tetrahydro benzo [b] pyran derivatives. These unique derivatives were synthesized through condensation reactions enolizable compounds, different aldehydes, malononitrile (or ethyl cyanoacetate) under mild reaction conditions, in short times, gives excellent yields refluxing H2O green solvent. The accuracy...
ABSTRACT: In this study, Ag nanoparticles were loaded successfully into poly acrylic acid hydrogel (PAA) as a matrix to prepare PAA-Ag nanocomposite catalyst. The prepared catalyst was characterized by scanning electron microscope (SEM), transmission (TEM), Fourier transform infrared spectrophotometer (FT‐IR), thermal gravimetric analyzer (TGA), inductively coupled plasma atomic emission spectrometer (ICP), and X‐Ray photoelectron spectroscope (XPS). with NaBH4 used degrade some common...
Background: Today, nanoparticles hold great promise in biomedical researches and applications including bacteria detection. The rapid sensitive outcomes of detection strategies using nanoparticle conjugates become determinative, especially bacterial outbreaks. In the current research, we focused on detecting V. cholera its toxin a thiocyanate/Au nanoparticle. Thiocyanate adsorbed strongly surface gold changed by enhancing plasmon resonance nanoparticles. Objective: This method is tried to...
Mesoporous material has a significant role in medicine, health care, environmental monitoring, sensing the hazardous agents, and fighting against viruses bacteria. Nano-silica sphere is an important member of mesoporous family that noticeably flourished biology, other industrial applications. Efficient one-pot multicomponent syntheses 2-amino-3-cyano-4H-pyran derivatives were carried out over readily available simply synthesized recyclable Hollow Silica Sphere (HMSS). Comparable yields...
