Successful development of a micro-total-analysis system (µTAS, lab-on-a-chip) is strictly
related to the degree of miniaturization, integration, autonomy, sensitivity, selectivity, and …

In this paper, we report on the development of a filter-free fluorescence sensor for the
detection of multiple fluorescence wavelengths from a solution of fluorescent dyes with …

This study aimed to report a compact microfluidic measurement system, based on a filter-
free multiple-wavelength sensor, that can selectively identify wavelengths without using an …

A portable wavelength detection system has potential applications in various fields,
