The synthesis of Janus nanoparticles requires the ability to selectively create each side of a nanometer sized particle with different chemical properties in a cost effective and reliable way that produces the particle of interest in high yield.
The synthesis of Janus nanoparticles requires the ability to selectively create each side of a nanometer sized particle with different chemical properties in a cost effective They can't be produced cost-ineffectively? Perhaps a commercially useful synthesis has these requirements and reliable way that produces the particle of interest in high yield.
