Bionanoparticles (BNPs) are pre-fabricated protein templates with a wide range of nanotechnology-related applications. In this review, we primarily focus on some modification strategies, ranging from basic protein conjugation techniques to more novel strategies, which expand the range of applications of these multimeric proteins.

Compared to bulk PbSe, the thermoelectric properties of individual solution-phase synthesized p-type PbSe nanowires exhibited a similar Seebeck coefficient and a significant reduction in thermal conductivity between 20 K and 300 K. After optimal annealing, single PbSe nanowires exhibited a thermoelectric figure of merit (ZT) of 0.12 at room temperature.

PtAu bimetallic nanostructures have been synthesized from Pt-on-Au colloidal nanoparticles. The composition of the resulting PtAu nanostructures is heterogeneous within the particles. Carbon-supported PtAu bimetallic heteronanostructures have much higher mass current density than pure Pt metal in the electrocatalytic oxidation of formic acid. Post-synthesis modification can be a very useful approach to the control of composition distributions in alloy nanostructures.
