An intermediate composite capable of transferring a biological or chemical material to be patterned on a surface. The intermediate composite includes a hydrogel, and particles suspended in the hydrogel, generating a particle-gel composite (composite), the composite is configured to absorb a biological or chemical material (agent), and further configured to deposit the agent when the composite is positioned proximate to a surface on which the agent is to be deposited.

The mat is formed of a saprophytic fungal strain and/or budding yeast, and a mass of particles wherein the fungus is characterized in producing an enzyme capable of breaking down polycyclic aromatic hydrocarbons. In a second embodiment, a mass of pellets is made from the mat for use in absorbing liquid animal waste.
