PLAUR and liver cancer: The duration of imaging was observed to be substantially extended from less than one hour to twelve hours, suggesting that the utilization of anti-VEGF PLA-PEG-PLL-Gd NPs as a nano contrast agent holds considerable promise for the early detection of liver cancers.375 Li et al. prepared a targeted uPAR nanoprobe DGLU11 by using endrograft poly-L-lysine (DGL) as a platform to couple the uPAR targeted peptide U11, gadolinium diethylenetriamine penta acetic acid (Gd DTPA), and cyanine dye cy5.5.
