According to Iran Nanotechnology Initiative Council (INIC), the protein studied in this research is antibacterial and the unusual amount of it in the body is a sign of disease.
Lysozyme is a protein found in tissues and secretions of mammals and in the egg white of bird eggs. The important role of lysozyme is its antibacterial properties. In fact, lysozyme is a natural antibiotic that helps the treatment of many diseases.
Unusual concentration of lysozyme in blood serum and urine can be a sign of diseases such as leukemia, kidney diseases and meningitis. Lysozyme also has larger applications in foodstuff and pharmaceutical industries due to its activity against bacteria cells, determined structure and low molecular weight. Therefore, it is important to measure lysozyme in the body. A nanobiosensor has been designed and produced based on gold nanoparticles in this research to measure lysozyme.
