abstract

• Hydroquinone is an aromatic organic molecule found in skin lightening creams for dermatological melasma treatment. The absorbance of this substance at high concentrations can be the cause of skin diseases. Nowadays most of the methods used for medical diagnosis for dermatological diseases consist on invasive methods such as biopsies. In recent years non-invasive techniques based on the properties of light and the interaction with biological samples have come to a new way for medical diagnosis. By means of Raman spectroscopy is of great interest the detection of hydroquinone for future medical applications. Due to the low Raman signal that the biological samples present, it is necessary to make use of nanotechnology. Making biosensors (SERS substrates) that allow us to amplify the electromagnetic field for the biological Raman signals. © 2107 SPIE.
