Integrity Screening Report: Self-Heating Multistage Microneedle Patch for Topical Therapy of Skin Cancer

Academic fraud report · Geng Detector

Summary

This report screens the Advanced Materials paper "Self-Heating Multistage Microneedle Patch for Topical Therapy of Skin Cancer" (DOI: 10.1002/adma.202308217) by Jundong Shao et al. for academic integrity concerns. The overall verdict is "questionable" (yellow), driven primarily by the absence of original image files rather than detected anomalies. Text-level methodological and logical checks passed: reagent and timeline consistency is internally coherent, with mature commercial materials (PLGA, HA, 5-FU, TQ, iron powder) and plausible degradation/observation windows (over 6 weeks). Experimental design across nine animal groups (n=5) shows coherent dose-response and combination effects, and mechanical data (drug-loaded 0.09 N/needle vs blank 0.14 N/needle) is consistent with polymer science. Image-level forensics (reuse, splicing, blot manipulation) could not be performed because only text and captions were available. Confidence is therefore limited to textual integrity; pixel-level analysis of Figure 1-6 remains pending.

Verdict

🟡 Questionable — No text-level integrity issues detected; image-level forensic analysis pending due to lack of original images.

Key findings

Methodology and timeline consistency (PASS): All reported reagents (PLGA, HA, 5-FU, TQ, micron-scale iron powder) are commercially established; PLGA degradation timeline (>6 weeks) aligns with the reported animal observation window (>6 weeks). Submission-to-acceptance timeline (Aug–Dec 2023) is within normal peer-review norms.
Core experimental logic and data plausibility (PASS): Mechanical data show reduced needle strength upon drug loading (0.09 N/needle vs 0.14 N/needle), consistent with expected polymer matrix disruption. Nine-arm in vivo design (control, monotherapy, combination, multistage release, self-heating, etc.) yields a coherent staircase of tumor inhibition rates; pure-heat arms show mild ablation effects, drug-only multistage arms show early efficacy with late relapse, and the combined self-heating + multistage arm sustains inhibition beyond 6 weeks.
Image forensics (INCONCLUSIVE): Pixel-level checks (Figure 1–Figure 6) could not be performed because only text and captions were supplied; no textual evidence of figure-text conflict was found, but absence of original images precludes splicing, cloning, or Western blot manipulation analysis.

Evidence highlights

DOI: 10.1002/adma.202308217
Mechanical strength: 0.09 N/needle (drug-loaded) vs 0.14 N/needle (blank) — Figure 2e
Animal study: n=5 per group, 9 groups, observation >6 weeks — Figures 4, 6
Submission window: Aug 2023 submission → Dec 2023 acceptance
PLGA degradation window reported as >6 weeks, matching in vivo observation period
Iron-powder self-heating mechanism analogous to commercial disposable warmers; no anachronistic reagents noted

Notes

The "questionable" rating reflects uncertainty from missing image evidence, not from any positive finding of misconduct.
Suggested follow-up for strict peer review or PubPeer scrutiny: obtain Supporting Information raw data, particularly the individual tumor growth curves in Figure 6c, plus all original microscopy and fluorescence images, to check for selective exclusion of animal subjects or image reuse/splicing.
This automated report is an AI-assisted screening aid and does not constitute a formal finding of academic misconduct. Final determinations require investigation by qualified institutions.
