Nanoscale and Nanoscale Advances are delighted to introduce the new themed collection “Magnetic Nanoparticles: From Massart Method to a Cascade of Innovations”. All articles in the collection are free to read from 01 September until 12 October 2026.
Magnetic nanoparticles are a class of materials that exhibit unique superparamagnetic properties due to their nanoscale size and high surface-to-volume ratio. The synthesis of magnetic nanoparticles is central to their widespread use, with several methods developed over the years to produce them in a controlled, reproducible manner.
One of the most well-known and widely adopted methods is the alkaline co-precipitation method developed by Prof. René Massart in the early 1980s. Originally conducted in water (though it can be adapted to a dispersed state in less polar media), it is a widely used, cost-effective technique for synthesizing magnetic nanoparticles, especially iron oxide (magnetite and maghemite), as well as other spinel-structured metal oxides (e.g., cobalt, manganese, and zinc ferrites). Known for its simplicity, up-scalability, and ability to relatively control particle size and magnetic properties, the Massart process is extensively employed for producing nanomaterials for in biomedical, environmental, and industrial applications due to its efficiency and versatility in producing large quantities of tailored nanoparticles.
This themed collection aims to provide a comprehensive overview of the advances in the field of magnetic nanoparticle research, by covering its different facets ranging from rational design of synthesis processes to improved properties dispersion states, and end applications.
In tribute to René Massart, this collection covers various aspects of magnetic nanoparticles, including:
- Synthesis and design of magnetic nanoparticles
- Characterization of magnetic nanoparticle structure, dynamics, and properties
- Surface functionalization and dispersion state of magnetic nanoparticles
- New methodologies of magnetic nanoparticles synthesis in the bulk
- Flow chemistry synthesis of magnetic nanoparticles
- Study of nucleation and growth of magnetic nanoparticles
- Multifunctional magnetic based nanoparticles, including (bio)organic nano-assemblies and nano(bio)hybrids
- Structure-properties relationships of magnetic nanoparticles and magnetic based nano(bio)hybrids
- Biomedical applications of magnetic nanoparticles (targeted drug delivery, magnetic resonance imaging (MRI), magnetic particle imaging (MPI), hyperthermia treatment, and in vitro or in vivo biodegradation studies
- Environmental applications (water treatment and micropollutant detection or removal)
- Industrial or energy-related applications (magnetic storage media, seals, valves, construction materials, and magnetically boosted catalysis, e.g., for clean hydrogen production)
This themed collection is being guest edited by, Ali Abou-Hassan (Sorbonne University, France), Professors Nguyễn T. K. Thanh (University College London, United Kingdom), Teresa Pellegrino (Italian Institute of Technology, Italy ), Anna Cristina S. Samia (Case Western Reserve University, United States), Olivier Sandre (University of Bordeaux, France) and Lise-Marie Lacroix (Toulouse University, France).
