Scanning electron microscopy (JSM 4900LV; JEOL Ltd., Japan) was used to acquire microphotographs on the surface and cross-section of the freshly prepared extrudates. To improve conductivity prior to examination, samples were coated with gold using a Polaron SC7640 sputter gold coater (Quorum Technologies, UK).

For the purpose of comparison, fresh and aged samples at different conditions were scanned using JSM 5900LV Field Emission Scanning Electron Microscope (Jeol Ltd, Japan) equipped with a tungsten hairpin electron gun. Surfaces and cross sections (prepared by cutting the samples after dipping into liquid nitrogen) of all samples were investigated for the presence or absence of crystal growth and changes in the microstructure of the matrices. The scanned samples were coated with gold using a Polaron SC7640 sputter gold coater (Quorum Technologies, Newhaven, UK) prior to imaging.

SEM Analysis of SMD Film Morphology

Check if the same lab product or an alternative is used in the 5 most similar protocols
Scanning electron microscopy (SEM) (JSM 4900LV; JEOL Ltd., Japan) images were collected on freshly prepared films to investigate SMD film morphology and particle size analysis. To improve conductivity prior to examination, samples were coated with 20 nm of gold under vacuum using a PolaronSC7640 sputter gold coater (Quorum Technologies, UK). The average diameter of the drug was determined from the mean value of 100 measurements using ImageJ (USA, version 1.46v).
The particle size of formulated OLZ in SMD films was measured. Prior to the analysis a weighed amount of film was dissolved in distilled water (120 mL) using a Hydro MV Mastersizer 3000 (Malvern; Grovewood Road, UK) at a rotational speed of 2800 rpm.

Scanning Electron Microscopy of Zein Films

Check if the same lab product or an alternative is used in the 5 most similar protocols
The surface morphology of zein alone and HAS/Zein free films as well as morphology of coated tablets were studied using SEM. Samples were mounted onto stubs using double-sided tape and were gold coated by a Polaron SC7640 sputter gold coater manufactured by Quorum Technologies (UK). The thickness of the gold coating was about 15 nm. The imaging process was performed in a high vacuum environment with a JEOL JSM5900 LV SEM (Japan), mounted with a tungsten filament with an acceleration voltage of 5-20 kV.

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.
