Nickel nanoparticles are used in magnetic and catalytic applications. The reference article describes the use of the magnetic properties for biological applications. By binding them to biomolecules, the small size high surface area makes them superior bioseparation agents compared to conventional micrometer-sized beads. The authors use 13 nm superparamagnetic Ni/NiO core-shell particles. The diameter where the nickel nanoparticles start to undergo spontaneous thermal fluctuations at room temperature is around 17 nm and the single domain threshold lies at 24 nm.

Key trends at the nanoscale


The pie chart presented here is based on the distribution of research literature across various fields of application research over the period 1992 to 2017. The value listed is the number of papers discussing Nickel related to nanoparticles, sorted by application field. This gives an indication which applications are being or have been researched and where the core interest is. However, the distribution does not correct for the total publications in a given application field. So, a high score for a given application field indicates there is considerable interest in the element in that field, but it may also mean the field itself has considerable more publications than other fields. Therefore, the pie chart gives a general overview only. The application fields themselves are discussed in more detail on our Nanoparticles page.

Additionally, the total number of publications provides some insight in the amount of research into Nickel used in nanoparticles in general. Typically, a well-researched element will show 1000 or more publications over the 1992-2017 period.

Alloys and composites

The graph below presents an analysis of literature on core-shell, alloy and composite particles with nickel as a component of such nanoparticles. It shows possible combinations for alloy or composite nanoparticles and reflects research interest during the 1992-2017 period.
