Native BSA was selected as the model molecular probe because its hydrodynamic radius of approximately 7 nm in ambient conditions provides a viable distance between fluorophores and plasmonic surface [34]. BSA was covalently modified with CF488A, CF555, and CF647 by amine-NHS crosslinking. Each f...
although the bioimaging signal continuously decreased, it was still able to effectively distinguish the positive group (I response of 25.44%) and NTC group (I response of 11.20%). It could be concluded that EBV cfDNA was closely related to CNE-Luc cells. However, naked-eye visualization was u...
