The samples are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, charge-discharge measurements and electrochemical impedance spectroscopy.
For angiogenesis analysis, three random 0.151 mm fields at 200× magnification within tumor core and tumor front were captured using a fluorescence microscopy charge-coupled device color camera (cell^R – Imaging Station; Olympus, Hamburg, Germany).
The structure and performance of the samples are characterized by powder X-ray diffraction, atomic absorption spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, galvanostatic charge-discharge and electrochemical impedance spectroscopy.
The cellulose nanowhiskers were characterized using transmission electron microscopy, and their charge surface density was determined by a titration method.
[158] CdSe QDs modified with mercaptoundecanoic acid (MUA), mercaptopropionic acid (MPA), aminoundecanoic acid (AUA), or cysteamine (CA) 3, 5, and 10 nm 0.5, 5, 20, 80, and 160 μg/ml; 22 h NHBE WST-1; LDH assay; ELISA; fluorescent microscopy The positively charged (AUA- and CA-modified) QDs are more toxic than the negatively charged (MUA- and MPA-modified) QDs.
This technique combines laser light scattering microscopy with a charge-coupled device (CCD) camera, which enables the visualization and recording of nanoparticles in solution.
Fluorescence microscopy of negatively charged giant unilamellar vesicles with AlexFluor-647-labeled Chex1-Arg20 dimers and tetramers displayed aggregation at a peptide/lipid low ratio of 1 200 and at higher peptide concentrations (1 100/1 50) for Chex1-Arg20 monomer.
Based on our previous finding that room temperature ionic liquid (RTIL) can be observed by scanning electron microscopy (SEM) without charging of the liquid, a specifically designed electrochemical cell has been developed to observe electrochemical metal deposition from RTIL in real time by SEM.
The most commonly used type of imaging sensor within microscopy is the charged coupled device (CCD) sensor.
