Feb 24, 2022 · Polyacrylamide (PAM) is a water-soluble, synthetic polymer that acts as a highly effective binding agent with fine silts and clays. These particles are bound together with PAM to form flocs, which can settle out of the water to significantly reduce turbidity. This process is described in more detail in Soil Facts AG (see reference section).

Designing hydrogels for controlled drug delivery

The high water content (typically 70–99%) provides physical similarity to tissues, and can give the hydrogels excellent biocompatibility and the capability to easily encapsulate hydrophilic drugs. Moreover, because they are typically formed in aqueous solutions, the risk of drug denaturation and aggregation upon exposure to organic solvents ...
