A dual-mode green emissive fluorescent probe for real-time detection of doxycycline in milk using a smartphone sensing platform

Abstract

Real-time quantitative analysis of tetracyclines is urgent to provide consumers with risk early warning. Herein, we report a dual-mode green emissive fluorescent probes which refers to the liquid mode and...

A portable fluorescence detection device based on a smartphone employing carbon nanodots for Mn2+ sensing

“…While numerous reports have discussed the application of carbon dots and smartphones for fluorescence detection, they have yet to address the high selectivity of Mn 2+ detection via a smartphone. While there have been reports on the employment of smartphones for fluorescence detection, 21,46–48 the suggested portable fluorescence device-based smartphone is distinct. This work uses the macro lens to decrease the focal distance of the newly designed portable fluorescence-based smartphone, an extremely compact device.…”

“…Thus, the smartphone application can analyze the fluorescence emission signal detected with the camera in the digital image platform as a useful analytical signal. 20–22 The current research development in the smartphone application shows promise for processing the obtained pictures into RGB signals in one step. 23–25…”
