In this work we present results of our calculations of CdTe/ZnTe core/shell quantum dots (QDs) of very small size capable for targeted bioimaging. The transition energy of the electron and hole system confined in a CdTe/ZnTe core/shell sphere is obtained by the effective-mass approximation. Optical properties are analyzed as function of QD size and spatial composition and compared to already known experimental results. CdTe/ZnTe core/shell-structured QDs are perspective to use in biomedical applications because: they exhibit strong luminescence and low toxicity (compared to the CdTe QD); shell of wide-gap semiconductor protects core from degradation; they have long-term colloidal and optical stability; their surface can be passivated with biocompatible functional molecules; they can be produced in small size, less than 5 nm. These properties enable their use for targeted bioimiging..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
