Fingerprints are one of the most frequently found evidence in crime scenes and are widely recognized as a tool for human personal identification. The nature of fingerprints varies at the scene of the crime on a circumstantial basis such as visible, three-dimensional, and latent fingerprints. The latent prints require the use of imaging techniques. Among the established routine methods for fingerprint development is the use of commercially available black and white powder. Although this method is relatively fast, simple, and cheap, but can cause harmful hazards and health risks to users due to the use of fine particles such as titanium dioxide, lead, and mercury-based powders. Therefore, there is a growing need to find alternate powders that are easy to prepare, cost-effective, and non-toxic in nature. This study proposes to develop an alternate powder that can be produced by potato peel that is considered as a food waste, it is a much cheaper, simple, and readily available option. The finding of the study revealed that the powder of potato peel is capable of visualizing latent fingerprints on non-porous surfaces such as sunmica, glass, polished steel, iron metal etc. The frictional ridges were very clear and all the minutiae can be used for comparison and record purposes. This study also opens up the scope of further study in this way.
