“…Point-of-use devices, such as granular activated carbon filters can be highly effective for removing lead, chlorine, undesirable taste and odor VOCs, and other chemicals in the water . While it is well-known that such filters elevate microbial numbers at the tap, , research is required to understand how such filters could potentially be manipulated to support beneficial microbiomes.…”

The "exposome" is a term describing the summation of one's lifetime exposure to microbes and chemicals. Such exposures are now recognized as major drivers of human health and disease. Because humans spend ∼90% of their time indoors, the built environment exposome merits particular attention. Herein we utilize an engineering perspective to advance understanding of the factors that shape the built environment exposome and its influence on human wellness and disease, while simultaneously informing development of a framework for intentionally controlling the exposome to protect public health. Historically, engineers have been focused on controlling chemical and physical contaminants and on eradicating microbes; however, there is a growing awareness of the role of "beneficial" microbes. Here we consider the potential to selectively control the materials and chemistry of the built environment to positively influence the microbial and chemical components of the indoor exposome. Finally, we discuss research gaps that must be addressed to enable intentional engineering design, including the need to define a "healthy" built environment exposome and how to control it.

“…Bacteria can be found in the air, soil, and water and play central roles in ecosystems. However, bacterial contamination poses a huge threat to global public health, affecting the food industry, hospital diagnostics, and society [ 1 , 2 , 3 , 4 ]. According to the Centers for Disease Control and Prevention (CDC), around 48 million people suffer from diseases caused by foodborne pathogens every year.…”

Bacterial contamination is a public health concern worldwide causing enormous social and economic losses. For early diagnosis and adequate management to prevent or treat pathogen-related illnesses, extensive effort has been put into the development of pathogenic bacterial detection systems. Colorimetric sensing systems have attracted increasing attention due to their simple and single-site operation, rapid signal readout with the naked eye, ability to operate without external instruments, portability, compact design, and low cost. In this article, recent trends and advances in colorimetric systems for the detection and monitoring of bacterial contamination are reviewed. This article focuses on pathogen detection strategies and technologies based on reaction factors that affect the color change for visual readout. Reactions used in each strategy are introduced by dividing them into the following five categories: external pH change-induced pH indicator reactions, intracellular enzyme-catalyzed chromogenic reactions, enzyme-like nanoparticle (NP)-catalyzed substrate reactions, NP aggregation-based reactions, and NP accumulation-based reactions. Some recently developed colorimetric systems are introduced, and their challenges and strategies to improve the sensing performance are discussed.

“…The ability of these filters to sequester P. aeruginosa effectively depends on the duration and frequency of usage as well as water quality. Efficiency of membrane POU water filtration has been demonstrated but some studies report that P. aeruginosa contamination can occur within the recommended term of usage given by the manufacturer [9,10].…”
