In addition, the bacteria can be changed so that they themselves can produce toxins while they multiply in the body. In comparison with pure toxin, only a very small dose of bacteria is then needed to achieve full effect. There are large opportunities to further develop weapons based on biotechnology. After studies of structure-activity relationships for certain toxins and substances produced within the body, it is possible to develop modified and even more active substances. Improved knowledge of receptors on the cell surface, for example as a result of cancer research, ill make it possible to target toxic substances to selected organs.
Weapons based on biotechnology today are probably still within the research or developmental stages.
In the long-term, they may become a serious threat.
