The use of colloids for controlled assemblies stem from the fact that perfect sphere or even Janus nanoparticles are capable of unique geometries that result in arrays or patterned films with functiona properties useful for applications such as sensors, devices, and drug delivery. The use of colloidal-nanosphere-lithographic (CNL) methods forming 2-Dimensional arrays are well known in photonics and band-gap structures. We have demonstrated the use of hybrid nanoparticl dendrimer assemblies capable of charge transfer and electron-transfer mediated transitions for possible display device applications. We have been involved in the use of CNL methods to fabricate arrays of electropolymerized and patterned systems for the preparation of functional films and sensors. In this talk, we will focus on the use of colloidal nanosphere lithography to fabrication different patterns of conducting polymers and grafted polymer brushes. More recently, we have demonstrated the use of these assembles to fabricate bilayer assembles of cow-pea-mosaic viruses (CPMV) in collaboration with the Steinmetz group for possible appplications in viral therapeutic applications.
