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 …

Method to convert organic waste matter into a carbon material

Carbon Microspheres

Northern China’s roadsides are peppered with deciduous phoenix trees, producing an abundance of fallen leaves in autumn. These leaves are generally burned in the colder season, exacerbating the country’s air pollution problem. Investigators in Shandong, China, recently discovered a new method to convert this organic waste matter into a porous …
