An enzyme-free amplification strategy based on two-photon fluorescent carbon dots for monitoring miR-9 in live neurons and brain tissues of Alzheimer's disease mice.

An enzyme-free amplification strategy based on two-photon fluorescent carbon dots for monitoring miR-9 in live neurons and brain tissues of Alzheimer's disease (AD) mice. Notably, using our developed probe, miR-9 was found to be up-regulated in early onset AD, while it was found to be down regulated to lower than the normal level in late onset AD.
