Apr 1, 2023 · Transmission electron microscopy (TEM) and atomic force microscopy (AFM) were employed to observe the morphology and microstructure of the synthesized CNQDs-PEG. TEM and high-resolution TEM images of CNQDs -PEG were collected using a Tecnai G2 TF20 system at an accelerating voltage of 200 kV.

TEM may work if can use a modified PEG end-group designed to couple selectively with a contrast agent. You could use a terminal sulfur to bind gold nanoparticles, or a chelating group to bind...

Our findings indicate that TEM grid supported, polymerized NTA lipid monolayers are capable of capturing His-tag protein targets in a manner that controls their areal densities, while efficiently blocking non-specific adsorption and limiting film degradation, even upon …

Polyethylene glycol (PEG) coating of gold nanoparticles (AuNPs) improves AuNP distribution via blood circulation. The use of PEG-coated AuNPs was shown to result in acute injuries to the liver, kidney, and spleen, but long-term toxicity has not been well studied.

Jan 5, 2019 · A way to prepare PEGylated Au NPs by sputtering of Au into pure (PEG), thiol (PEG-SH) and amine terminated polyethylene glycols (PEG-NH 2) was explored. Structural characterizations, aging and thermal stability were performed using transmission electron microscope (TEM/HRTEM) and UV–vis spectroscopy.

A poly (ethylene glycol)-poly (lactic acid) block-copolymer (PEG-PLA) was first prepared and characterized using H-NMR spectrum and DSC thermogram. This block-copolymer was used for the optimization of preparing PEG-PLA tyrosinase nanocapsules.

In the present study, solid-sphere nanoparticles (SNPs) made of poly (ethylene glycol)- b -poly ( ε -caprolactone) (PEG- b -PCL) were covalently linked to a monoclonal antibody (83-14 mAb)...

Our findings indicate that TEM grid supported, polymerized NTA lipid monolayers are capable of capturing His-tag protein targets in a manner that controls their areal densities, while efficiently blocking nonspecific adsorption and limiting film degradation, even …

Nano silver particles with an average mean crystallite size of between 10 and 12 nm were synthesized from different molecular weights of poly (ethylene glycol) as a stabilizing agents, through...

Jan 19, 2016 · Our findings indicate that TEM grid supported, polymerized NTA lipid monolayers are capable of capturing His-tag protein targets in a manner that controls their areal densities, while efficiently blocking nonspecific adsorption and limiting film degradation, even upon prolonged detergent exposure.
