Use of proteins and peptides to synthesize inorganic materials for different applications has advantages over other methods. Selection of the peptides is performed by biopanning technique. In this technique, the desired material is screened against million copies of phage display library, and phages, with higher affinity, are selected and sequenced. This method to synthesize inorganic materials is relatively benign and inexpensive. Moreover, peptides can create crystalline ceramics in ambient conditions. In this work, we explored use of proteins and peptides for patterning and depositing gold and ceramic nanoparticles on silicon-based and nickel-coated substrates. Covalent immobilization of the peptides on the substrates was performed to increase density of the peptides on the substrates. Physical adsorption of the peptides was also used to compare the results with the covalently bound peptides. For each material, a precursor solution was reacted with the immobilized peptide. The peptides catalyzed deposition and formation of material particles on the substrates. The effects of reaction conditions such as pH and the solution concentration on the particles size and morphology were investigated as well. Moreover, photoluminescent property of crystaaline calcium molybdaye particles was tested for potential biosensing applications. SEM, TEM, EBIC, AFM, epifluorescence microscopy, confocal microscopy, and focused ion beam technique were used to characterize the samples.
