App Note | Technology: Quartz Crystal Microbalance
Why are protein – container enclosure interactions important? During manufacturing, storage and delivery processes, therapeutic proteins encounter several surfaces and materials, such as metals, glasses, oils, and polymers. These can range from stainless-steel production vessels to glass prefilled syringe delivery devices. The inherent surface-active nature…
App Note | Technology: Langmuir Blodgett
Langmuir-Blodgett (LB) deposition is a well-established method for generating monolayers of sample onto a substrate. A layer of molecules (or nanoparticles) are placed at the interface and compressed with barriers until they form a monolayer at the air-liquid interface, then a substrate is dipped through…
App Note | Technology: Scanning Electron Microscopy
Introduction The scanning electron microscope (SEM) is a powerful tool for taking very high magnification images of a variety of materials. It generates an image by scanning a beam of electrons across a sample’s surface and detecting the electrons generated through sample interactions. This type…
App Note | Technology: Optical Tensiometry
Contamination can have a wide variety of undesirable effects in manufacturing processes such as polishing, surface treatment, coating application, and etching. Some sources include finger oils from handling, atmospheric dust and dirt, and process lubricants. While best practices such as personal protective equipment use and…
App Note | Technology: Optical Tensiometry
For powdered materials such as pharmaceuticals, dyes, proppants, and foods, wettability is an important parameter to characterize. As the powders are immersed into a liquid, fluid may wick into the interstitial spaces between powder particles through capillary forces. The wettability of the powder can be…
