A lead-specific binding protein, PbrR, and promoter pbr from the lead resistance operon, pbr, of Cupriavidus metallidurans CH34 was incorporated into E. coli in conjunction with an engineered downstream RFP (red fluorescence protein), which allowed for highly sensitive selective whole-cell detection ions. The subsequent display PbrR on cell surface permitted adsorption ions solution containing various heavy metal surface-engineered bacteria effectively protected Arabidopsis thaliana seed...

The coordination bond between gold and sulfur (Au-S) has been widely studied utilized in many fields. However, detailed investigations on the basic nature of this are still lacking. A gold-specific binding protein, GolB, was recently identified, providing a unique opportunity for study Au-S at molecular level. We probed mechanical strength gold-sulfur GolB using single-molecule force spectroscopy. measured rupture to be 165 pN, much lower than bonds different surfaces (∼1000 pN). further...

Mercury contamination represents a global threat. A simple, sensitive, and rapid means of detecting trace mercury is urgently needed. Herein, we have developed series biosensors by combining quorum sensing-based positive feedback systems with mercury-specific operon, merR. Our results demonstrated that the sensitivity fluorescence intensity engineered E. coli cells were greatly improved thanks to system. In addition, fitting signals classic Hill equation, discovered responses close...

Detection and recovery of heavy metals from environmental sources is a major task in protection governance. Based on previous research into cell-based visual detection biological adsorption, we have developed novel system combining these two functions by the BioBrick technique. The gold-specific sensory gol regulon was assembled gold-chaperone GolB (Gold-specific binding protein), which responsible for selectively absorbing gold ions, this led to an integration with increased probe tolerance...

The decay of surface plasmons in metal nanostructures followed by the generation hot electrons has attracted widespread attention from researchers due to its potential for injecting into silicon generate photocurrent and achieve infrared photodetection. However, extremely low photoconversion efficiency limits their large-scale practical application. Despite extensive research on electron devices based various gold/silicon nanoholes (Au/Si NHs), understanding individual Au/Si NHs remains...
