DMTMM or the amine concentration so that a specific degree of substitution or crosslinking is achieved. The stability of DMTMM has also been examined, and degradation studies of DMTMM in H2O at 50 °C with 1H NMR analysis show that 11% of the starting material remains after 48 hours. The reaction has proven to be an from Sigma-Aldrich. All other reagents were purchased from a DMTMM solution (28 mg, 0.10 mmol; in 2 mL of 0.1Mboratebuffer,pH=8.5)wastransferreddropwise,andthe To remove excess DMTMM and unbound InvA497, nanoparticles were then centrifuged three times in Centrisart® tubes as mentioned above, at 1605 g and 4°C, for 10 min each cycle. In order to produce InvA497-functionalized aspherical nanoparticles, spherical PLGA nanoparticles were first incubated for 2 h with DMTMM as described above.
