One property of gold nanoparticles stands in the way of many nanotechnological developments: They're sticky. Gold nanoparticles can be engineered to attract specific biomolecules, but they also stick to many other unintended particles - often making them inefficient at their designated task. MIT researchers have found a way to turn this drawback into an advantage.

Read moreDamit die Dosis eines Medikaments kuenftig so niedrig wie therapeutisch moeglich gehalten werden kann, sollen die Wirkstoffe in Zukunft direkt zum Zielort im Organismus transportiert und dort erst freigesetzt werden. Dafuer sollen sie in Nanopartikel eingeschlossen werden, die ihre Fracht nur bei einem bestimmten pH-Wert, einer definierten Temperatur oder unter anderen spezifischen Bedingungen freigeben.

Physical adsorption is a technique used to characterize the surface and pore features of solids, that is, the materials texture. The adsorption isotherm generated by the Physical Adsorption technique enables one to characterize a solids' texture by determining its surface area, porosity, and total pore volume.
