Research project title(s): 

  • Influence of Surface Coordination on the Magnetic Properties of Magnetic Nanoparticles / Ph.D. Assoc. Prof. Yousef Najajreh.
  • Engineered nanoparticles used for entomopathogenic fungi mycosynthesis / Dr. Rana Samara.

Science case and possible benefit:

Influence of Surface Coordination on the Magnetic Properties of Magnetic Nanoparticles: addressing such research is critical for the understanding the correlation of the physicochemical properties of outer-surface bound ligands on the magnetization and will be relevant for research towards biomedical application (magnetic hyperthermia, magnetic particle imaging of cancer, magnetic targeting, gene and drug delivery and manipulation of the immune system by macrophage polarization for cancer treatment.

Applications of nanoparticles in agriculture and their role in disease management: lead of the investigation of environmental risk assessment.

Short summary of main expected outputs/ results:

Influence of Surface Coordination on the Magnetic Properties of Magnetic Nanoparticles

  1. Understanding the effect of the decorative coating ligands on the magnetization Superparamagnetic Iron Oxide Nanoparticles (SPIONs)

  2. Explore the correlation between the outer sphere physicochemical characteristics and the distribution of and magnetization inside SPIONs.
  3. Creating knowledge and understanding of factors impacting SPIONs magnetization.
  4. Qualifying the next generation of scientists by offering them proper training in synthetic chemistry and physics techniques.
  5. Producing and disseminating knowledge relevant to
  6. Explore the potential biomedical application of modified SPIONs.

Applications of nanoparticles in agriculture and their role in disease management: Synthesis of inexpensive nanoparticles bio-pesticides, which includes local indigenous microbial bio-agents (entomopathogenic fungi, bacteria and viruses...ect) or indigenous essential oils and plant extracts.

Expected future impact, including directly in the Palestinian (research) community: These projects will lay the ground for long-lasting collaboration upon which the following will be achieved:

  1. Training: Palestinian master students will get trained in synthetic chemistry as well as in methods for characterization of functionalized MNPs. In addition, bachelor students will be recruited to conduct their graduation projects. The project will offer the students the possibility to get an insight into competitive international and interdisciplinary research setting.
  2. Capacity building: progress in the proposed projects will allow for recruiting more further PhD students and researchers. The project will offer the possibility for the students to proceed in international competitive settings towards their PhD and Post doctorate fellowships.
  3. Joint publications and international meetings: it is anticipated that results stemming from the project will be submitted to highly ranked scientific journals and presented in interactional scientific gatherings.
  4. Exchange experiences, share knowledge via joint workshops and seminars. More collaborations.  
  5. Provide excellent career prospects to the fellows.
  6. Shape a new generation of young researchers that will no longer be hampered by the traditional boundaries of disciplines shaped centuries ago.  

Future plans:

  1. Establish an internet platform for a permanent information exchange
  2. Extend my collaborations with more Palestinian / non-Palestinian Scientist working in nanoscience.
  3. Establish my own research group in Palestine by keeping a connection with FZJ and German universities. 
  4. Collaboration with the large facilities around the worldwide (SESAME, DESY, FRMII, ILL, NIST, ....etc)
  5. Construction of lab infrastructure for NPs synthesis, sample preparation and for a local characterization such as SEM

Future vision for the PGSB/research in Palestine or general:

  1. PGSB will provide a highly qualified new generation of young Palestinian researchers with advanced research skills.
  2. Possibility of establishing long-term new cooperation’s between Palestinian and German universities not only with FZJ. 
  3. Setting up a new PhD programs at Palestinian universities by taking benefits from the advance knowledge and skills of PGSB alumni.
  4. Possibility of more lab infrastructure using benefits of the collaboration with German universities and research centers which facilitate getting a funding of an infrastructure.  
  5. Establishing new research fields / Creating and launching a new university courses
