Journal ArticleDOI
Microscale Heat Transfer Transduced by Surface Plasmon Resonant Gold Nanoparticles.
TL;DR: Temperature in =10-microliter aqueous suspensions of 20-nanometer gold particles irradiated by a continuous wave Ar+ ion laser at 514 nm increased to a maximum equilibrium value in proportion to incident laser power and to nanoparticle content at low concentration.
Journal ArticleDOI
Separation of biomolecules using adsorptive membranes
TL;DR: A review of adsorptive separations using affinity, ion exchange and hydrophobic membranes can be found in this paper, where the authors show that these membranes exhibit low backpressure, short residence times and high volumetric throughputs relative to conventional chromatographic packed beds.
Journal ArticleDOI
