The development of high-carbon-content polymers for optoelectronics is an area of intense research; however, carbon-rich materials have certain limitations that arise from their composition. Some of these limitations can be overcome by the judicious incorporation of heavier elements which do not significantly change the carbon content to a point where it adversely …

A similar mechanism most likely occurs with TeNSs. The soluble tellurium derivative released by Te-containing NSs is probably tellurite, which in turn can damage E. coli cells . Tellurite release was suggested by TEM, with the observation of tellurium nanorods inside E. coli after being exposed to Te-based nanostructures (not shown). These ...
