Fig. 2From: Tumor specific liposomes improve detection of pancreatic adenocarcinoma in vivo using optoacoustic tomography a DLS measurements to determine the size of the liposomes. The liposomes are approximately 129 nm in diameter with a polydispersion index of 0.05. b Zeta-potential measurements of the liposomes. Z = 0.3 mV. c Transmission electron microscopy of the liposomes. The average size of the liposomes as determined by TEM is approximately 117 nmBack to article page
