A rice kind of fingerprint powder
A new method for producing print powders goes against the grain
Revealing fingerprints using powders has been a staple of sleuthing science for nearly 130 years, with prints developed this way still the leading identification method for crimes worldwide. Yet despite its age and widespread use, latent print development using fingerprint powder is still very much an active area of research, with each new technique allowing us to process more ridge detail, on more surfaces and under a variety of conditions. Even something as seemingly ‘solved’ as fingerprint powder can benefit from a makeover.
