My GQDS were made from glucose dissolved in water and heated in a microwave. I want to transfer them onto a Si substrate and then transfer graphene using a wet-transfer method. However, when I place my Si substrate with a drop of my GQD solution into water, the GQDS disperse into the water. I have tried heating them and spin-coating them onto the Si, but they do not stick. What can I do? If I methylate the Si substrate will that work??
