Negative stain

Electron micrograph of positivity stained (organic) plant tissue without (top) and with OsO4 staining
Identification of lamellar(le), reverse-miceller(M) and reverse-hexagonal H-II cylinders(H) lipid phases by negative staining.

Negative staining is an established method, often used in diagnostic microscopy, for contrasting a thin specimen with an optically opaque fluid. In this technique, the background is stained, leaving the actual specimen untouched, and thus visible. This contrasts with 'positive staining', in which the actual specimen is stained.
