Rapid measurement of the waterborne pathogen Pseudomonas aeruginosa in different spiked water sources using electrochemical sensing: Towards on-site applications
نویسندگان
چکیده
Pseudomonas aeruginosa is a waterborne ubiquitous opportunistic pathogen that can be fatal for immunocompromised patients. Here, we report the use of paper-based screen-printed sensors electrochemical detection P. in water sources only 14 s. identifiable by its unique biomarker pyocyanin, which redox-active and therefore suitable direct without sample pretreatment. The method was applied to detect pyocyanin directly spiked lake water, tap sea groundwater. response linearly proportional concentration with R2 values between 0.9918 0.9991. Additionally, demonstrated concentrations ranging from 5 50 colonies/mL. results are step towards utilizing simple sensing rapidly determine if infected prior bathing, consumption or other use.

Rapid Waterborne Pathogen Detection with Mobile Electronics
Pathogen detection in water samples, without complex and time consuming procedures such as fluorescent-labeling or culture-based incubation, is essential to public safety. We propose an immunoagglutination-based protocol together with the microfluidic device to quantify pathogen levels directly from water samples. Utilizing ubiquitous complementary metal-oxide-semiconductor (CMOS) imagers from ...
