Four-way parallel factor analysis of voltammetric four-way dataset for monitoring the etoposide-DNA interaction with its binding constant determination

In this paper, a novel strategy in the application of the parallel factor analysis (PARAFAC) to a four-way voltammetric dataset was improved to evidence the interaction of etoposide (ETO) and calf thymus deoxyribonucleic acid (DNA) to determine the ETO-DNA binding constant. PARAFAC is one of the most commonly used techniques applicable to the decomposition of higher-order data arrays to focus on features of interest and provides a different...
