In the majority of these cases, it can possibly trigger allergic reactions or toxic effects (1). A 77-year-old woman came to our observation 3 months after the onset of extensive urticaria. For a flu-like syndrome, she took azithromycin 400 mg about 24 hours before the event, and an homeopathic product for flu-like symptoms, (Omeogriphi Guna containing Aconitum napellus 5CH, Belladonna 5 CH, Echinacea Angustifolia 3CH, Vincetoxicum 5CH, Anas barbariae hepatis and cordis extractum 200K, Influenzinum 9CH) about 1 hour before the event.

Surface modification of GQDs was carried out using polyethylene glycol (PEG) for conjugation with protoporphyrin IX (PpIX). Synthesized GQDs (Se 0.3%) at 180°C had an emission spectrum that fairly coincided with the absorption profile of PpIX. A relative decrease of about 62.48% in the emission intensity of anthracene was recorded under illumination with UVC light in the presence of GQDs (Se 0.3%) and the reduction for clung GQDs (Se 0.3%) and PpIX during 90 min was about 70.68%. Singlet oxygen (1 O2 ) generation was examined using a chemical method that showed significant enhancement in decomposition rate constant in clung GQDs-PEG-PpIX compared with GQDs and PpIX alone. Afterglow over 600 s showed that
