DESI-MSI Fingerprint Imaging Data with Bleeding Effect Analysis

A 4.7 MB dataset from figshare authored by R. Krishna in April 2026 dissects the application of Desorption Electrospray Ionization Mass Spectrometry Imaging (DESI-MSI) to fingerprint imaging. The work explores advantages and challenges, including a specific delocalization phenomenon termed 'the bleeding effect' observed in fingerprints. It includes a description of the effect, methods to minimize it, and implications for operational work.

Use Cases

• Compare DESI-MSI performance against MALDI-MSI for fingerprint imaging based on the described advantages and challenges.
• Analyze the 'bleeding effect' delocalization phenomenon specific to fingerprint samples mentioned in the description.
• Optimize DESI-MSI operating conditions for fingerprint analysis based on the discussed methods to minimize the bleeding effect.
• Assess the suitability of DESI-MSI for forensic molecular fingerprinting based on the comparative uptake analysis presented.

Strengths

• Dataset is 4.7 MB, indicating a manageable download size.
• Focuses on a specific, described phenomenon ('bleeding effect') in fingerprint imaging.
• Author provides a discussion of operational implications and minimization strategies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect methodological bias inherent to the specific experimental setup described.
