Protein Hydrogel for Cancer Theranostics
Funded by the Science Fund of the Republic of Serbia – PROMIS program 2020-2022
Implemented by the University of Belgrade – Faculty of Physical Chemistry
Grant no: 6062285
Duration: 10 July 2020 – 10 July 2022
- Bringing molecular imaging to the forefront in cancer research
- Advancing biomedical applications of electron paramagnetic resonance (EPR) imaging
- Design and development of novel methodologies using EPR spectroscopy and imaging for the measurement of albumin hydrogel drug release kinetics and water content, and visualization of albumin hydrogel degradation
- Design and development of an anticancer drug depot-anchoring albumin hydrogel prototype intended for molecular imaging of treatment response which can enter preclinical trials
Why EPR imaging?
- Nanomolar detection limit
- Variable sample volume
- Experiment time and cost efficiency
- EPR “active” compounds (spin labels & spin probes) are non-toxic and applicable in vivo
- Real-time visualization of the hydrogel position, size and shape
- The image contains information on the redox environment and oxygen concentration

We are the only EPR team in Serbia which performs in vivo spectroscopy and imaging, and measurements at T = 4K.
Our main lines of research include: Effects of lipophilicity and terminal groups on anticancer drug activities; Liposomes as drug carriers and model membranes; PLGA nanoparticles for drug delivery; In vivo spectroscopy and imaging of oxidative status in Alzheimer’s disease and ALS; Metal content of brain tissue.
