Printing cAbs onto the dry brush without excipient results in their stable immobilization within the brush and avoids bleeding or dissolution of taxi places upon hydration with biological matrix. This leads to uniform capture spot morphology, which assists in quantification and evaluation. In contrast, publishing detection reagents with an excess of soluble excipient onto the completely dry brush creates a storage tank for assay reagents. Call with blood or other aqueous fluid triggers dissolution of the excipient in printed spots of the dAb and releases the dAb from the chip, and also the launched dAb openly diffuses across the surface area as well as drives the assay to completion. The direct inkjet printing of reagents onto POEGMA brush is another crucial element of the D4 assay, as it allows precise control over assay geometry, place focus, as well as structure, without the demand for covalent coupling actions, which streamlines assay manufacture.
