What Are Latent Fingerprints and Why Are They Crucial

Latent fingerprints are invisible prints left on surfaces due to secretions from skin glands. These prints, composed of sweat, oils, and other biological residues, are often difficult to detect without specialized methods.

Traditional techniques like black powder dusting or cyanoacrylate fuming have served forensic science well but have limitationsespecially with partial, faint, or aged prints.

Silica Gel G Powder: A Forensic Innovation

Silica Gel G powdercomprised of silica and gypsum boasts polar OH groups that enhance its ability to bind with the moisture and oils in latent prints. It delivers:

• High sensitivity, revealing even faint or partial fingerprints.
• Versatility across a wide range of substrates glass, plastic, metal, paper, wood, and more.
• Non-destructive results, preserving both the prints and underlying material.
• Availability and ease of application, making it a practical solution in real-world forensic labs.
