Abstract: In this study, the carbon dots (CDs) were prepared from the rubber latex (Hevea brasiliensis) as the carbon source and ammonium persulphate as the nitrogen source using microwave-assisted pyrolysis. Various instrumental techniques such as transmission electron microscopy, UV-visible spectrophotometer, fluorescent spectrophotometer and fourier-transform infrared spectroscopy were employed to characterize CDs. The particle size of synthesized CDs was less than 5 nm in size and CDs showed good optical properties and solubility in water. The optical properties of CDs were strongly influenced by several functional groups (-OH, -CHO, -COOH, -CO, -COO) formed on the CDs surface. Finally, the CDs were applied as a fluorescent probe for the selective and sensitive detection for tyrosine. The CD-based sensor showed an excellent applicability for the tyrosine detection
