摘要： This invention provides antibacterial and antiviral compositions and methods. The compositions possess prolonged and powerful antibacterial/antiviral functions under light exposure and even under completely dark conditions, while daylight exposures could recharge the functions repeatedly. In some embodiments, compositions of the invention can be employed in personal protective equipment (PPE) such as face masks, biologically self-cleaning air and water filters, medical devices, and products. The biocidal PPE can prevent transmission of infectious diseases such as Ebola and respiratory viruses. In some embodiments, compositions of the invention can be employed in food protectant materials to provide antimicrobial and antiviral bio-protection during food transportation and storage.

摘要： Methods and kits for detection of alkylating agents are described. The present invention discloses methods and kits comprising sensors for the rapid detection of chemical agents (e.g., alkylating agents) at low concentrations. The methods are useful for the detection of alkylating agents such as field fumigants such as methyl bromide or methyl iodide. The detection can advantageously be performed by a change in light absorbance of the sensor moiety using the naked eye.
