Dual applications of oil-rich coal-based carbon dots: sensitive detection of Cr( vi ) and fingerprint imaging

Key Points

• This research focuses on developing fluorescent probes for sensitive detection of chromium and their use in fingerprint imaging.
• Synthesis of oil-rich coal-based carbon dots (ORC-CDs)
• Fluorescence-based detection in actual water samples
• Application in imaging fingerprints
• Demonstrated rapid detection of Cr(vi) with high sensitivity
• Practical applicability in environmental monitoring and forensic science
