A multifunctional basic pH indicator probe for distinguishable detection of Co 2+ , Cu 2+ and Zn 2+ with its utility in mitotracking and monitoring cytoplasmic viscosity in apoptotic cells

at basic pH. Furthermore, the probe displays its utility in mitotracking and monitoring cytoplasmic viscosity changes in SiHa cells. It is efficiently used to recognize the apoptosis process by displaying an enhancement in fluorescence intensity from cancerous SiHa cells to apoptotic cells.
