    • Synthetic trials experimenting with the length of the alkyl spacer between the TMMA and thiosulfate groups were performed, and the seven-carbon spacer met the requirements of stabilization to the Au core, desired solubility in water, and successful Ln3+binding.

    • note
    • It should be noted that the selectivity of the MHTMMA NPs declines as metal ion concentrations increase, as an aliquot of 1 M Pb3+ induced a color change in the particle solution. This is not expected to impact the utility of the sensor, as the level of this ion is typically in the parts per billion range, well below the concentration that induced particle interaction.
