Neuro-Fuzzy Concentration Classifier for Microplastics in Saline Solution
Summary
This paper describes a neuro-fuzzy concentration classifier designed to detect tiny concentrations of micro- and nanoplastics in saline solution, an important step toward detecting plastics in biological tissues. The approach demonstrated the ability to distinguish microplastic concentrations in a complex liquid medium.
Micro and nano plastic have been detected in almost every tissue in the human body. The main goal of medical researchers today is to determine if the presence of microplastics in tissue is toxic for humans. Therefore, the most immediate challenge is to find a method of measurement that determines the presence of micro and nano plastic in living tissue. This paper presents research efforts to find a method for detecting tiny concentrations of microplastics in a saline solution. Authors have previously developed a bioimpedance spectrum measurement technology for studying biological processes in cells. The measurement method is non-invasive, without the use of any hazardous materials or processes. In this study, plastic beads of 6 micrometer diameters were implemented in different concentrations. The results of the proposed classifier method were compared with previous results obtained by using the Cole-Cole model, indicating improvement in accuracy and correlation detection.
