Match the given latent print detection technique to the surfaces on which they can be used. using ninhydrin
fuming with superglue fuming
fuming with iodine
dusting with carbon powder
exposing to silver nitrate
using magna brush
Porous Surface
Non-porous Surface

using ninhydrin: porous surface

fuming with superglue fuming: non-porous surface and porous surface

fuming with iodine: non-porous

dusting with carbon powder: non-porous

exposing to silver nitrate: non-porous

using magna brush: non-porous

Explanation:

The ninhydrin method and superglue fuming can be done on porous and non-porous surfaces. The ninhydrin readily combines with the amino acid present in the latent print.

The fuming with iodine and silver nitrate react with the salts present in latent print and they act on non-porous surfaces.

Carbon powder and magna brush also works on non-porous latent print.
