The bioactivity of most near-infrared II (NIRII) fluorophores are limited, thereby conflicting the achievement of strong fluorescence and high catalytic activities, due to a lack of free electrons in the method.
First insights into engineering crystal growth by atomically precise metal nanoclusters have been achieved in a study performed by researchers in Singapore, Saudi Arabia and Finland. The work was published in Nature Chemistry.
