^aThe correlation was tested for five types (n = 5) of MPs (PB, PE, PP, PS, and PVC)/four types (n = 4) of MPs (PB, PE, PP, and PVC) and the SARS-CoV-2 RNA fragment; the magnitude of correlation coefficient (R) reflects the degree of correlation between the E_int and molecular parameter values; the bold numbers indicate high values of the correlation coefficients (R > 0.800); the numbers marked in both bold and italic indicate a significant correlation at the 0.05 level (p < 0.05).
