Isothermal titration calorimetry studies on the binding of amino acids to gold nanoparticles
Article Abstract:
The use of isothermal titration colorimetry (ITC) to study the binding of ligands such as amino acids to the surface of inorganic materials such as gold nanoparticles is reported. The analysis of binding strength of lysine and aspartic acid with aqueous gold nanoparticles at pH11 by ITC revealed strong binding of aspartic acid and weak binding of lysine to gold nanoparticles.

Direct synthesis of branched gold nanocrystals and their transformation into spherical nanoparticles
Article Abstract:
A facile synthesis of branched gold nanocrystals by the addition of a suitable amount of NaOH to an aqueous solution of cetyltrimethylammonium bromide (CTAB), HAu[Cl.sub.4], and ascorbic acid is reported. It is found that the branched nanocrystals quickly transformed into spherical nanoparticles within 1 h of reaction, and the process was essentially complete after 2 days.
