Delivery systems biological agents

A pharmacotectonics concept was illustrated by researchers, in which drug-delivery systems were arranged spatially in tissues to shape concentration fields for potent agents. NGF-releasing implants placed within 1-2 mm of the treatment site enhanced the biological function of cellular targets, whereas identical implants placed mm from the target site of treatment produced no beneficial effect (Mahoney and Saltzman, 1999). Because of some limitations with controlled delivery systems, alternatives such as encapsulation of cells that secrete these factors are discussed in the next section. [Pg.66]

Regardless of what t3rpe of formulation is employed in the field, the formulation must wet, disperse, and remain homogeneous in the application spray equipment. Careful selection of formulating agents, commonly called inerts, is extremely important. These ingredients have no biological activity of their own, but combined, they function as the delivery system for the pesticide. [Pg.88]
