Desktop STEM as a Sample Screening Tool for Cryo-EM
Sample preparation for cryogenic electron microscopy (cryo-EM) can be a demanding and expensive process, requiring several rounds of purification and screening to isolate the macromolecules of interest. Negative stain electron microscopy (EM) is one of the established tools for the initial screening of purified samples, specifically for assessment of particle size, morphology, concentration, and agglomeration. […]
How does Surface Roughness Affect Contact Angle Measurements?
Contact angle measurements with an optical tensiometer can be quick, non-destructive, and straightforward measurements to characterize surface chemistry and understand the interaction of a surface with a liquid of interest. Young’s equation (Figure 1A) defines the measured contact angle as a function of the surface tension of the liquid, the surface energy of the solid, […]
Empowering Nanofibers: Enhancing Usability and Overcoming Production Challenges
Nanofibers, or fibers with diameters on the scale of 10-9 meters, exhibit unique properties, differing significantly from the properties of the bulk materials. These include a large surface area to volume ratio, high porosity, high encapsulation efficiency, superior mechanical properties, and higher chemical stability. As a result of these remarkable properties, some versatile materials have found their way into a multitude of applications with the potential to address critical challenges in numerous fields and lead to a more sustainable and technologically advanced future.
