High-efficiency transfer of fingerprints from various surfaces using nanofibrillated cellulose

Fingerprint transfer and detection by fluorescent NFC/CDs paper. Compared with cyanoacrylate fuming and dusting with black powder, we can transfer clear fingerprint patterns from rubber substrate onto NFC/CDs paper. The results of feature points extraction and similarity assessment show that 80% of the feature can transfer from smooth substrates and 60% from rough substrates.
