The most commonly used method for the covalent binding of biomolecules onto 1-D nanostructures is through the diimide-activated amidation of carboxylic acid terminated nanostructures.
Thermogravimetry analysis(TGA) and Dynamic Stress Rheometer(DSR) were used to measure the conversion and viscosity changing with time during the thermopolymerization to form polythioetherimides.
