Abstract

Thrombus formation issues play an important role in the occurrence, diagnosis and treatment of cardiovascular diseases. The inhibition of platelet aggregation is currently the main therapeutic approach in treatment and prevention of cardiovascular diseases. Understanding the platelet structure and its spectral response to the antiplatelet therapy is the key to personalized medicine today. According to the World Health Organization (WHO) reports, cardiovascular deceases have been remaining the leading cause of death at the global level for the last two decades. The number of deaths has been increased up to nearly 9 million in 2019 [1]. The COVID-19 pandemic has resulted in cardiovascular decease (CVD) increase, which caused deaths in many countries [2-3]. The paper presents studies of the fluorescence intensity of aromatic amino acids namely tyrosine (Tyr) and tryptophan (Trp) in the presence of spherical rhodium and platinum nanoparticles (Rh and Pt NPs).
