Introduction to Gold Nanoparticles – Properties & Applications in Life Science


Gold nanoparticles are particles with diameters in the 1-100 nm range and have unique optical and physical properties, the most pronounced being the intense absorbance and scattering of incident light at its surface plasmon resonance wavelength.

The optical properties of gold nanoparticles are governed by their morphology, i.e. size, shape and aggregation status. By precisely engineering particles with different morphologies and surface chemistries, these particles can be tuned to suit a variety of applications making them a very versatile research and diagnostic tool. For example, the gold nanoparticle surface can readily be functionalized with peptides, proteins and antibodies providing them with specificity toward cellular targets both in vitro and in vivo. In addition, modifying the surface with oligonucleotides enables them to be used for genetic detection. Common applications include their use in immunohistochemistry, bioimaging, biosensors, lateral flow assays, as cellular probes, and as vehicles for drug delivery.

Dr. Pacheco received his PhD in cell and molecular biology from Lund University, Sweden where he studied the biosynthesis of the complex carbohydrate chondroitin/dermatan sulfate. He furthered his scientific career by moving to Canada where he first completed post-doctoral training at the Structural Genomics Consortium and later, at University of Toronto. It was at this time he became familiar with the field of nanotechnology, especially in regards to the synthesis and applications of nanomaterials. This led him to join Cytodiagnostics Inc., where he was an integral driving force to spur the company’s growth from inception into one of the leading nanomaterial suppliers in the work for the life sciences market. He now holds the position as Chief Scientific Officer.
