Abstract
Tellurium nanowires synthesized using green chemistry methods and having unique morphologies and functional properties are provided. The nanowires have a core of hexagonal crystal phase tellurium and a polymer coating, and can be used for treating cancer without apparent cytotoxicity toward normal human cells.
Claims7
Coated tellurium nano wires having a core comprising tellurium and an outer coating comprising a polymer, wherein the polymer is starch, and wherein the coated tellurium nanowires are produced by a method comprising the steps of:
- (a) heating an aqueous solution or suspension comprising telluric acid (H2Te O4) and starch in a sealed vessel at a temperature from about 120° C. to about 200° C. for about 2 hours to about 20 hours;
- (b) centrifuging the product from step (a) to obtain a pellet;
- (c) resuspending the pellet in an aqueous solution;
- and
- (d) lyophilizing the resuspended pellet resulting from (c), whereby the coated tellurium nanowires are produced;
- and wherein at least a portion of the produced coated tellurium nano wires form a star-shaped structure comprising coated tellurium nanowires radiating outwards from a central point.
