Abstract: The disclosure provides for protein-coated micro- or nano-particles that can be used as reference standards for assessing technical variations in microfluidic devices.

Abstract: There are provided methods for producing a hydrogel that is capable of adhesion of cells and which comprises enzymatically cross-linked conjugates of a hydrogel forming agent and a flavonoid, formed from a reaction using peroxide and peroxidase. Hydrogels produced by such methods and methods of using the hydrogels are also provided.

Abstract: There is provided methods for producing a hydrogel comprising conjugates of a hydrogel forming agent and a flavonoid including a method for producing a hydrogel that is capable of adhesion of cells and which comprises enzymatically cross-linked conjugates of a hydrogel forming agent and a flavonoid. There is also provided a method for producing a hydrogel comprising conjugates of a hydrogel forming agent and a flavonoid without the addition of an exogenous peroxide or peroxidase or without the addition of an exogenous peroxide. Hydrogels produced by such methods and methods of using the hydrogels are also described herein.
