Nano-sized carrier systems find medical application

Comparison of nanomaterials_sizes

Nano-sized carrier systems find medical application to improve pharmacologic properties of bioactive agents. For many therapeutic approaches, it is important that the carrier system can stably incorporate the cargo during circulation without inducing aggregation, while cargo should ideally only be released after successful cellular uptake. These requirements have thus far …
