Plant biosensor systems

Abstract The invention provides a system for monitoring the bio-availability and or toxicity of contaminants in the environment. The system includes plant biosensors that indicate the presence of contaminants, such as, for example, volatile organics or heavy metals, using an in situ monitoring approach. The plant biosensors are genetically engineered to exhibit a change in [...]

Toxicity issues in the application of carbon nanotubes to biological systems

Abstract Carbon nanotubes (CNTs) have recently emerged as a new option for possible use in methodologies of cancer treatment, bioengineering, and gene therapy. This review analyzes the potential, through possible toxicologic implications, of CNTs in nanomedicine. Generally, proven success in other fields may not translate to the use of CNTs in medicine for reasons including [...]

Recent advances in biosensor techniques for environmental monitoring

Abstract Biosensors for environmental applications continue to show advances and improvements in areas such as sensitivity, selectivity and simplicity. In addition to detecting and measuring specific compounds or compound classes such as pesticides, hazardous industrial chemicals, toxic metals, and pathogenic bacteria, biosensors and bioanalytical assays have been designed to measure biological effects such as cytotoxicity, [...]
