In vitro intracellular PL lifetime thermal sensing using CDs. a PL emission decays of HeLa cells incubated with CDs (500 μg/mL) at different temperatures (Tset). b Temperatures determined using the calibration (Tmeas) and set temperatures (Tset) plotted against the PL lifetime. cf Applicability of CDs for long-term remote intracellular temperature monitoring. c PL lifetimes extracted from PL transients recorded every 15 min for 24 h of HeLa cells incubated with CDs (500 μg/mL). d Temperatures determined using the calibration curve. e Temperatures measured with a reference thermometer (Tref). f Histogram showing the distribution of temperature differences between the obtained and reference temperatures; the solid line is the distribution curve.
