1. E wehewehe ʻia kahi ala hou no ka hoʻonui ʻana i ka ninhydrin a i ʻole 1,8-diazafluoren-9-one (DFO)-treated latent fingerprints ma ka pepa wela.ʻO ka hapa nui o nā ʻili wela o ka pepa wela e lilo i pōʻeleʻele ke mālama ʻia me ka solution DFO a i ʻole ninhydrin petroleum ether (NPB).Hoʻemi kēia hopena i ka ʻokoʻa ma waena o nā manamana lima i kūkulu ʻia a me ke kua.ʻO ke ala hou i wehewehe ʻia e hōʻemi i kēia ʻeleʻele ʻeleʻele me ka wehe ʻole ʻana i ka papa thermosensitive a me nā ʻāpana o nā manamana lima i kūkulu ʻia, e like me ka holoi ʻana i ka acetone.Ma o ke ʻano hou, ʻike ʻia nā manamana lima i kūkulu ʻia i nā laina ʻoi a me ka ʻokoʻa kiʻekiʻe.Ua hana ʻia nā hoʻāʻo nui, e alakaʻi ana i kahi hopena hana maikaʻi loa, ka mea e hoʻopiʻi i ka pepa me ka liʻiliʻi o nā kemika, maʻalahi, a hiki ke mālama ʻia ka nui o nā pepa i ka manawa pōkole.Loaʻa i ka hopena hana nā mea kūʻai aku, nonvolatile, nitrogenous organic compounds a hiki ke hoʻohana ʻia e like me ka hoʻohana ʻana i ka solution NPB ma ke kaomi ʻana.
2. Hōʻike kēia pepa i ke aʻo ʻana o ka hopena ma waena o 1, 8-diazafluoren-9-one (DFO) me ka amino acid L-alanine i ka methyl alcohol.Ua uku ʻia ka uku hoihoi i ke kuleana o ka mea hoʻoheheʻe i ʻike ʻia e hana pū me ka DFO e hana i kahi hemiketal ʻo ia ka ʻano reactive.Manaʻo ʻia kahi ala hoʻololi ma muli o ka ʻikepili o kēia manawa i hōʻiliʻili ʻia.Ua ʻike ʻia nā mea waena a me nā huahana e nā ʻano hana spectroscopic like ʻole me mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy, a me X-ray crystallography.
