Smartphone-based autofluorescence imaging to detect bacterial species on laboratory surfaces

Abstract

This work demonstrated instantaneous, reagent- and staining-free, smartphone-based autofluorescence detection of bacterial contamination on typical laboratory desk surfaces. Detection was successfully distinguished from protein, salt, and tap water.

Arrayed labeling-free cultivation and growth evaluation from a single microorganism

“…33 Bao et al reported the labeling-free and quantitative evaluation of the growth behavior of microorganisms enclosed in microdevices by autouorescence. [34][35][36][37] However, the method is not suitable for the cultivation of several thousand single cells individually since the method was not equipped with multiply compartmentalized cultivation spaces.…”
