ABSTRACT
Current techniques identifying herbal medicine species require marker labeling or lack systematical accuracy (expert authentication). There is an emerging interest in developing an accurate and label-free tool for herbal medicine authentication. Here, a high-resolution microfluidic-based method is developed for identifying herbal species by protoplast subpopulations. Moso bamboo and henon bamboo are used as a model to be differentiated based on protoplast. Their biophysical properties factors are characterized to be 7.09 (± 0.39) × 108 V/m2 and 6.54 (± 0.26) × 108 V/m2, respectively. Their biophysical distributions could be distinguished by the Cramér-von Mises criterion with a 94.60% confidence level. The subpopulations of each were compared with conventional flow cytometry indicating the existence of subpopulations and the differences between the two species. The subsets divided by a biophysical factor of 8.05(± 0.51) × 108 V/m2 suggest good consistency with flow cytometry. The work demonstrated the possibility of microfluidics manipulation on protoplast for medication safety use taking advantage of dielectrophoresis. The device is promising in developing a reliable and accurate way of identifying herbal species with difficulties in authentication.
