19 Claims

1. A functional fibrous material, comprising:

a plurality of fibers;

a plurality of micro-flakes;

wherein each micro-flake of the plurality of micro-flakes is composed of a hydrogel;

wherein the hydrogel is crosslinked;

wherein at least one microorganism is embedded in the hydrogel;

wherein each micro-flake of the plurality of micro-flakes has at least one sheet-like protruding edge;

wherein a plurality of sheet-like protruding edges of the plurality of micro-flakes are, at least partially, wrapped around the plurality of fibers so that the plurality of micro-flakes are entangled with the plurality of fibers; and

wherein, when in a presence of electrolytes, the at least one microorganism is released from the functional fibrous material.
