TEM Characterization of Biosynthesized AgNPs

The biosynthesized AgNPs were morphologically characterized by a transmission electron microscope (JEOL model 2100, Japan). The microscope was operated at an optimum accelerating voltage of 200 kV. A few drops of re-dispersed AgNPs were placed on a carbon-coated copper TEM grids and allowed for 10 min to settle down, followed by observation under the microscope.

Comprehensive Polymer Characterization

The FTIR spectra of the polymers were obtained using a Bruker Equinox 55 Fourier transform infrared spectrometer (Bruker, Billerica, MA, USA) (frequency range 4,000 to 500 cm^-1). The UV-vis spectra of the samples were recorded on a UV-vis spectrophotometer (UV4802, Unico, Dayton, NJ, USA). Raman spectra were recorded in a backscattering geometry with a 1,064-nm excitation wavelength using a Bruker Vertex 70 FT infrared spectrometer (equipped with RamIIFT Raman Module). XRD patterns have been obtained using a Bruker AXS D8 diffractometer with a monochromatic Cu-Kα radiation source (λ = 0.15418 nm); the scan range (2θ) was 10° to 80°. Morphology and microstructure of the samples were investigated by FESEM (Hitachi S-4800, Hitachi Ltd., Chiyoda-ku, Japan). TEM measurements were performed on a TEM instrument (JEOL model 2100, JEOL Ltd., Tokyo, Japan).

Virus samples were treated with MβCD for 30 min at 37 °C before being washed thrice at 2000 × g for 3 min each in Amicon concentrators (100 kDa MWCO). Samples were fixed in solution containing 1% para-formaldehyde and 0.1% glutaraldehyde at 4 °C for 15 min. Samples were washed again before being mixed with 1% osmium tetroxide and incubated with gentle shaking at 4 °C for 1 h. Samples were washed seven times with deionized water before being concentrated to a volume of 100 μL and loaded on lacey carbon grids (EM Microscopy) and dried overnight. Just before imaging, samples were stained with 0.1% uranyl acetate and rinsed. Imaging was performed on a transmission electron microscopy (TEM) system (JEOL, Model 2100) at 120 keV.

Characterization of Nanocomposite Films

Check if the same lab product or an alternative is used in the 5 most similar protocols

The cross-sectional scanning electron microscope (SEM) images of the nanocomposite films were captured using the Tescan-MIRA field-emission scanning electron microscopy. The morphology of the Fe3O4 nanoparticles was analysed by transmission electron microscopy (JEOL, model 2100). The tensile behaviours of the (4 mm × 25 mm) composite films were measured by applying a 1 mm/min load using the MTS Tytron 250 Micro-force Tester. The toughness, defined as the ability of a material to absorb energy up to fracture, was calculated using the OriginPro 8.5 software by integrating the area under the tensile stress-strain curves. The NETZSCH STA 449F3 instrument was used to perform the thermogravimetric analysis (TGA), and the samples were heated from 30 °C to 800 °C in N2 atmosphere with a heating rate of 5 °C/min. Fourier transform infrared spectroscopy (FTIR) spectra were obtained using an ATR spectrometer (5700 Nicolet Diamond). The X-ray diffraction (XRD) data were collected using the Bruker D8 with Cu Kα radiation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
