AB  - Large amounts of hazardous and toxic substances in the environment require non-toxic, cheap, easy, rapid, and 
sensitive methods for their detection. Blue luminescent graphene quantum dots (GQDs) were produced by 
electrochemical cleavage of graphite electrodes followed by gamma irradiation in the presence of ethylenedi amine (EDA). Modified dots were able to detect metal ions (Co2+, Pd2+, Fe3+) due to photoluminescence 
quenching. The highest sensitivity was detected for the sample irradiated at a dose of 25 kGy. The limits of 
detection (LODs) were 1.79, 2.55, and 0.66 μmol L− 1 for Co2+, Fe3+, and Pd2+, respectively. It was observed that 
GQDs irradiated at 200 kGy act as an ultra-sensitive turn-on probe for Malathion detection with LOD of 94 nmol 
L− 1
. Atomic force microscopy images proved the aggregation of GQDs in the presence of the investigated metal 
ions. Results obtained by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and LIVE/ 
DEAD cytotoxicity test indicated that GQDs irradiated with EDA are not toxic towards MRC-5 cells, which makes 
them a promising, eco-friendly and safe material for sensing application.
