Surface enhanced Raman spectroscopy sensor based on silver nanoparticles/multi wall carbon nanotubes for ultrasensitive detection of cholesterol.

Cholesterol is vital for living things because of an important part of cell membranes, as well as one of the basic components of brain and nerve cells. However, cholesterol must be at an optimum level. If it is below or above this level, it is a marker of many various diseases.

Ultrasensitive detection of amoxicillin using the plasmonic silver nanocube as SERS active substrate.

Even though amoxicillin is used as an antibacterial drug in some foods such as fish, chick, etc. However, the use of amoxicillin in the food industry is prohibited. Therefore, rapid detection and sensitive detection at ultra-low concentration of amoxicillin is very important for human.
