Claim:
1. A synthesis method in aqueous medium of cadmium-tellurium quantum dots joined with glutathione (CdTe-GSH), CHARACTERIZED in that it comprises the steps of: a. preparing an aqueous soluble cadmium salt solution in a buffer, the aqueous soluble cadmium salt solution having a pH of 9-13, the buffer being selected from the group consisting of a citrate buffer, a phosphate buffer, a Tris-HCL buffer, a Luria Bertani (LB) bacterial culture media buffer, and a MP buffer; b. adding glutathione (GHS) to the cadmium salt solution while applying agitation to from an agitated solution; c. adding a tellurium oxyanion as a tellurium donor, to the agitated solution of step b, the tellurium oxyanion being selected from the group consisting of sodium tellurite and potassium tellurite to from a composition; d. heating the composition from step c from 37° C. to 130° C. to from a reaction to provide a reactant solution; e. stopping the reaction by cooling the reactant solution to 4° C. to from a cooled solution; and f. incubating the cooled solution for at least 30 minutes.
