“…The limit of detection of ATP was 0.5 μM. 112 Recently, in another study, Patra et al synthesized three different nanocapsules as follows: liposomal Cur coated with a layer of PDDA, liposomal Cur coated with PDDA–silica–PDDA layer and the last nanocapsule consists of liposomal Cur–PDDA–silica–Cur–PDDA layer. They found that the fluorescence intensity of Cur in these nanocapsules considerably increased by 25, 54 and 62-fold, respectively.…”
