(a) The relationship between DNA concentrations and the absorbance of five different kinds of DNA in the range of 0-476.19 fM measured at the wavelength of 273 nm. Error bars represent the standard deviations of seven measurements. (b) The percentage change in the absorbance of five different DNA bacteria.
