Solid, free-flowing, and substantially completely dissolvable preparations with high betalain content are presented. A conducting element comprising a first portion, a second portion and a third portion between the first portion and the second portion is provided. The method then includes depositing a second resist layer on the substrate. The diagnostic assays may further involve manipulation of membrane potential by incubation of cells in K+-free buffer andor incubation with one or more compounds that alter Na+K+ ATPase activity. In the various embodiments, the augmented coverage configuration file correlates the services for overlapping cells on different frequency carriers enabling the mobile device to determine the available services without having to scan additional frequency carriers.
