Characteristics of nanocomplexes with iron Fe$^{3+}$ in glass ionomer cement powder by ESR method

The study is part of nanomedical biotechnology and is carried out by probing these systems using the Electronic Spin Resonance (ESR) method. The paper investigates Glass Ionomer Cement powder widely used in dental practice Glass Ionomer Cement C–Plus Triplekit–TM. To assess the quality of Glass Ionomer Cement and use ESR radiospectroscopy in the range from low ($T$ = 4.2 K) to room ($T$ = 300 K) temperatures. A new characteristic of compounds with nanocomplexes of magnetic iron ions Fe$^{3+}$ is applied.
