“…Since this seminal work, a number of reviews dealing with the developments and applications of organic fluorescent nanoparticles have been published. These reviews have highlighted small organic molecules [ 9 , 14 , 15 ], conjugated polymer nanoparticles [ 3 , 16 ], aggregation-induced emission dots [ 17 , 18 , 19 ], carbon dots [ 20 , 21 ], and up-conversion nanoparticles [ 22 ]. Some of these reviews cover very broad topics, including the synthesis of organic and polymeric materials and the preparation of NPs, whereas others focus on applications, including sensing [ 23 ], imaging [ 24 ], and diagnostic and therapeutic potential (phototherapy).…”
