Fig. 4From: Intracisternal delivery of PEG-coated gold nanoparticles results in high brain penetrance and long-lasting stabilityICP-OES analysis of brain Au contents. Adult mice received ICM injections of Cy5.5-AuNPs or vehicle and brains were collected 2 and 5 days after the delivery (n = 3 for each group). Plot reports means (± S.D.) of the total amount of Au (mg) found in the brain homogenates (mg) at each time pointBack to article page
