High Brightness

Definition

High brightness refers to the intense emission of light from a source, often quantified in terms of lumens or brightness levels, which is essential for visibility and imaging applications. In the context of quantum dots used for targeted drug delivery and theranostics, high brightness is crucial as it enhances the contrast and clarity of imaging techniques, making it easier to track and visualize the delivery of therapeutic agents within biological systems. This attribute not only improves diagnostic capabilities but also allows for real-time monitoring of treatment efficacy.
