    Abstract: Monodisperse carboxylate functionalized gold nanoparticles comprising a capping agent layer of pamoic acid and colloidal suspensions thereof are disclosed. These gold nanoparticles have an average particle size of greater than 15 nm or less than 8 nm and demonstrate significant fluorescent properties. In addition, a method for the size controlled preparation of these monodisperse carboxylate functionalized gold nanoparticles wherein pamoic acid acts as both a reducing and capping agent and wherein the size of the particles can be controlled by the pH of the process is disclosed. In addition, a method for the size controlled preparation of these monodisperse carboxylate functionalized gold nanoparticles utilizing seed mediated growth is disclosed.

    Abstract: The present disclosure provides an asymmetric supercapacitor that includes a negative electrode, a positive electrode, an ionic liquid electrolyte, and a separator. The negative electrode includes a tomato leaf activated carbon having a hierarchical porosity disposed on a first carbon cloth. The positive electrode includes a polyaniline disposed on a second carbon cloth; an ionic liquid electrolyte. The separator is located between the positive electrode and the negative electrode, and the ionic liquid electrolyte is present in and on the separator. The supercapacitor may be implemented in a heart pulse rate monitoring system.
