This work demonstrates the capabilities of nanoscale secondary-ion mass spectrometry, using the Cameca NanoSIMS50 ion microprobe, to detect and image the copper-ion distribution in microalgal cells exposed to nanomolar and micromolar copper concentrations. In parallel to (63)Cu(-) secondary-ion maps, images of (12)C(-), (12)C(14)N(-), and (31)P(-) secondary ions were collected and analysed. A correlation of (63)Cu(-) secondary-ion maps with those found for (12)C(14)N(-) and (31)P… CONTINUE READING
