Different Ways to Measure Viscosity

Measuring viscosity dates back to as early as the 19th century. French physicist Jean Poiseuille discovered the concept of measuring viscosity by formulating the "mathematical expression for the flow rate for the laminar flow of fluids in circular tubes." Later on, this formulation was discovered by a German hydraulic engineer Gotthilf Hagen, which came to be known as the Hagen-Poiseuille equation (Britannica). Early measurements of viscosity focused primarily on the flow of blood. Measurements were conducted using the hemodynamometer that incorporated narrow tubes & glass capillaries in effort to measure the pressures in the arteries of horses and dogs (Sutera).

LAPONITE - Use to Enhance Cell Growth & Drug Delivery

Laponite is an additive which is by definition, "a unique specialty additive; a layered silicate manufactured from naturally occurring inorganic mineral sources." The main purpose in which Laponite serves can be separated into two major uses:

1) Rheology Modifier — Laponite is added to various consumer products to improve stability; many products have been shear sensitive or thixotropic behavior. Laponite is often used as a thickener in cosmetics.

2) Film Former  Laponite produces film to create electrically conductive coatings

Aside from these two major uses, Laponite has been used in the healthcare industry as a bioink additive to hydrogels, enabling a habitable environment for stem cells and also playing a role in creating a biodegradable containment for drug delivery.
