Abstract
A composition comprising a plurality of particle clusters in a carrier, at least one particle cluster comprising a plurality of metal nanoparticles, wherein a configuration of the at least one particle cluster is such that the composition has an absorbance spectra peak of above about 900 nm. A method of making the composition comprising: reacting a metal nanoparticle precursor with a stabilizing agent to produce functionalized metal nanoparticles, dispersing the functionalized metal particles in a clustering agent to form the particle clusters; and re-suspending the particle clusters in a carrier to form the composition. Uses of the composition include as a contrast agent for imaging.
