semi-industrial synthesis of magnetic fe3o4@sio2@me nanopowder to visualization of latent fingerprints

In this study a magnetic nanopowder for the development of latent fingerprints in semi-industrial scale was prepared. instrumental techniques such as vsm and tem were used to characterize the nanopowders. to show that the achieved structure and properties are well-suited for forensic science, fingerprints developed using the fe3o4@sio2@me nanopowders were applied on the sheet of paper. the nanopowder, fe3o4@sio2@me, offers simple synthesis process, convenient use for routine casework and low price.
