Evaluation of cytotoxicity after tissue adhesives treatments using Raman spectroscopy.

(A) Averaged Raman spectra of L929 cells (a: control, b: PACA, c: Dermabond®) and the spectral differences of control and treated cells (d: control-PACA, e: control-Dermabond®, f: PACA-Dermabond®). (B) Relative intensities of the Raman peaks for control and treated cells with two tissue adhesives (PACA and Dermabond®).
