This paper evaluated the powdering of latent fingerprints with the cotton wool powdering technique.

Abstract

The powdering of latent fingerprints with the cotton wool powdering technique was evaluated on surfaces commonly encountered by fingerprint examiners at crime scenes. In addition, a large donor study was conducted using loaded and nonloaded samples from 20 donors. Results showed the technique to be an efficient and easy-to-use method that developed prints of comparable quality to those powdered with a squirrel-hair brush. (Published Abstract)
