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.

A simple method for efficient and rapid synthesis of one-dimensional hematite (α-Fe2O3) nanowires based on electrical resistive heating of iron wire at ambient conditions was proposed. The nanowire growth mechanism was thoroughly discussed.

High magnetic moment CoFe nanoparticles have been synthesized via the diffusion of Co and Fe in core/shell structured Co/Fe nanoparticles. These nanoparticles have high saturation magnetization up to 192 emu/g CoFe, and can be further stabilized after thermal annealing at 600 °C.

Novel Au–Ag alloy nanoporous nanotubes with tailored structural features and designed functionalities exhibit distinct optical properties and enhanced capability for electrochemiluminescence signal amplification, which make them particularly desirable as novel 1-D nano-carriers for biomedical, drug delivery and sensing applications.

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.

Using solid reducing agents, inorganic fullerene-like nanoparticles (IF) of WS2 and MoS2 have been synthesized from purely solid precursors. This method circumvents the use of toxic and hazardous gases, like H2S and hydrogen, in the synthesis of IF nanoparticles.
