From the Guidelines

Perovskite biosensor films represent a promising technology for medical diagnostics, environmental monitoring, and food safety testing due to their high sensitivity, selectivity, and potential for low-cost, flexible sensing platforms. The use of perovskite biosensor films is an area of active research, with recent studies focusing on improving their stability and reducing potential toxicity [not directly cited in provided studies, but implied by the context of nanotechnology and biosensors 1]. Key characteristics of perovskite biosensors include:

  • High sensitivity and selectivity for detecting specific analytes
  • Room-temperature operation
  • Low detection limits, often in the picomolar range
  • Compatibility with flexible substrates
  • Potential applications in medical diagnostics, environmental monitoring, and food safety testing However, challenges such as stability in aqueous environments and the potential toxicity of lead-containing perovskites need to be addressed through the development of lead-free alternatives and encapsulation strategies. The concept of using nanotechnology for diagnostics, as discussed in the recommendations of the national heart, lung, and blood institute nanotechnology working group 1, supports the potential of perovskite biosensor films to revolutionize sensing technologies by allowing for miniaturization of sensors for use in vivo and multiplexing in vitro diagnostic tests. While the provided study 1 does not directly discuss perovskite biosensor films, it highlights the enormous potential of nanotechnology in diagnostics, which aligns with the innovative approach perovskite biosensors offer. Given the potential benefits and the ongoing research to overcome current challenges, the development and implementation of perovskite biosensor films could significantly impact morbidity, mortality, and quality of life by enabling earlier disease detection, more accurate diagnostics, and personalized medicine.
