Diagrammatic structure (not to scale) of PB-MXNIR constructed on a PEGylated-PAMAM generation-4 dendrimer (ethylenediamine core) with AlexafluorR750 (AF750, internal reference) linked to surface amines (not shown) and cyanine5.5 (Cy5.5)-labeled peptide proteinase sensors, Cy5.5(Ahx)XXXX*XXXX(Ahx)C-, where the octapeptide (X) linker is designed to be cleaved by various MMPs (see Table 1).
