The present invention includes compositions and methods for selective binding of amino acid oligomers to semiconductor and elemental carbon-containing materials. One form of the present invention is a method for controlling the particle size of the semiconductor or elemental carbon-containing material by interacting an amino acid oligomer that specifically binds the material with solutions that can result in the formation of the material. The same method can be used to control the aspect ratio of the nanocrystal particles of the semiconductor material. Another form of the present invention is a method to create nanowires from the semiconductor or elemental carbon-containing material. Yet another form of the present invention is a biologic scaffold comprising a substrate capable of binding one or more biologic materials, one or more biologic materials attached to the substrate, and one or more elemental carbon-containing molecules attached to one or more biologic materials.

L'invention concerne des compositions et des procédés de liaison sélective d'oligomères d'acides aminés à des matériaux semi-conducteurs et à des matériaux contenant du carbone élémentaire. Un procédé de l'invention consiste à réguler les dimensions de la particule du matériau semi-conducteur ou du matériau contenant du carbone élémentaire par l'interaction d'un oligomère d'acide aminé qui, en particulier, lie le matériau à des solutions qui peuvent donner lieu à la formation du matériau. Le même procédé peut être utilisé pour réguler le rapport de forme des particules nanocristal du matériau semi-conducteur. Un autre procédé de l'invention consiste à créer des nanofils à partir du matériau semi-conducteur ou du matériau contenant le carbone élémentaire. Cependant, un autre aspect de l'invention est un échafaudage biologique comprenant un substrat pouvant lier un ou plusieurs matériaux biologiques, un ou plusieurs matériaux biologiques fixés au substrat, et une ou plusieurs molécules contenant du carbone élémentaire fixées à un ou plusieurs matériaux biologiques.
