Mapping tumor heterogeneity with quantum dots

Using a mixture of four quantum dots linked to antibodies that can detect cancer-associated proteins, a research team from Emory University has developed a method for mapping the molecular heterogeneity of human prostate tumor biopsies obtained from cancer patients. This method should be applicable to other types of tumors.

Prospects in the use of nanotechnologies in plant growing

Nanotechnologies in agriculture are mostly associated with the reproduction of agricultural species and the processing and improvement of the quality of production. Nanotechnologies are already being used for disinfection of the air and of various materials, including food for animals, for purification of water in agro-ecological systems, for the treatment of seeds and cultures, for stimulation of the growth and the development of plants, as well as for the development of new types of packing materials allowing the continuous preservation of the ready products.
