@MezaGordillo @LatinXChem Now that we know the method works under these conditions, one of the next steps is to build a low-cost colorimetric sensor, and determining these limits can be part of that process. (2/2)

@MezaGordillo @LatinXChem Hello, thank you for the question! So far, we have focused on refining the conditions at concentrations similar to those found in real samples. (1/2)

@OrgSynLujanLab @LatinXChem (2/2) Currently, we are testing with AMPA, a metabolite of glyphosate, which can be distinguished in the colorimetric detection due to the absorption band of the formed product.

@OrgSynLujanLab @LatinXChem (1/2) Good morning, Armando, thank you for the question, it's an excellent point! Although I haven't tested it on fruits or vegetables, we have tested this molecule with several commonly used pesticides and herbicides alongside glyphosate, and there was no interference.

@zapataivan @LatinXChem @ChemPhysChem @PCCP @RSC_Energy @beyondbenign @green_rsc @RSC_Sus Despite being faster, the pH 10.5 condition was maintained as it was the mildest condition in which the kinetic adjustment was successful.

[amanda @amcscheuer]

@zapataivan @LatinXChem @ChemPhysChem @PCCP @RSC_Energy @beyondbenign @green_rsc @RSC_Sus Yes, I've changed the pH of the media!
At lower pH levels, it was not possible to adjust the kinetics with the described equation. At higher pH levels, the value of k increased but remained in the same order of magnitude (10^-4), reaching near 8.8x10^-4 Lmol-1s-1 at pH 12. +
