Figure 4From: Raman imaging at biological interfaces: applications in breast cancer diagnosisH-bond interactions of interfacial water at biological interfaces. (A) dry sample, (B) wet sample; the blue line through the cartoon represents the tissue/water interfaces. The orange and green sites represent the hydrophilic moieties on the surface of the tissue. The red and white circles represent the oxygen and hydrogen atoms in water molecules, respectively.Back to article page
