The Manufacture and Tumour Cell Uptake of Nanoparticles Labelled with Fluorescein Isothiocyanate

Nanoparticles with a diameter of between 100 and 800 nm can be made from gelatin or albumin using a desolvation and hardening technique. Fluorescein isothiocyanate (FITC) can be bound to the surface of such nanoparticles. The conjugated gelatin nanoparticles were phagocytozed by some experimental tumour lines.
