Multiplexing Capabilities

Definition

Multiplexing capabilities refer to the ability to simultaneously transmit multiple signals or data streams through a single channel or medium. This is particularly significant in the context of quantum dots for biological sensing and imaging, as it allows researchers to monitor and analyze several biological processes at once, improving efficiency and the amount of information obtained from experiments.
