The Portable Chemical Sterilizer (PCS) is a revolutionary, energy-independent, almost waterless sterilization technology for Army medical units. The PCS generates chlorine dioxide from dry reagents mixed with water on-site, at-will, and at point-of-use (PoU) in a plastic suitcase. The Disinfectant-sprayer for Foods and ENvironmentally-friendly Sanitation (D-FENS) and the Disinfectant for ENvironmentally-friendly Decontamination, All-purpose (D-FEND ALL) produce aqueous chlorine dioxide in a...

Radical Substitution: Allylic Chlorination
0 Views •
2023
Typically, when alkenes react with halogens at low temperatures, an addition reaction occurs. However, upon increasing the temperature or under reaction conditions that form radicals, providing a low but steady concentration of halogen radicals, allylic substitution reaction is favored. This is because allylic hydrogens are very reactive as the formed intermediate is resonance stabilized. For example, when propene is treated with chlorine in the gas phase at 400 °C, it undergoes allylic...

Electrophilic Aromatic Substitution: Chlorination and Bromination of Benzene
0 Views •
2025
Chlorination and bromination are important classes of electrophilic aromatic substitutions, where benzene reacts with chlorine or bromine in the presence of a Lewis acid catalyst to give halogenated substitution products. A Lewis acid such as aluminium chloride or ferric chloride catalyzes the chlorination, and ferric bromide catalyzes the bromination reactions. During the bromination of alkenes, bromine polarizes and becomes electrophilic. However, in the bromination of benzene, the bromine...

In the current climate of scarce resources, new technologies are emerging that allow researchers to conduct studies cheaper, faster and with more precision. Here we describe the development of a bead-based salivary antibody multiplex immunoassay to measure human exposure to multiple environmental pathogens simultaneously.
FAQs
In water, chlorine chemistry produces hypochlorous acid and related oxidizing species that react with biological components. These reactions can disrupt proteins, lipids, membranes, and cellular function. The same reactivity that helps reduce contamination can also damage engineered biological systems when conditions are excessive, so bioengineering designs must balance antimicrobial performance against preservation of biological activity.
Chlorine exposure has outcomes that depend on whether the chemistry remains controlled or becomes excessive. Controlled exposure can support contamination reduction, whereas excessive exposure compromises cellular and tissue performance. This distinction is important when developing systems that protect living components, because the goal is to limit unwanted biological damage while retaining the intended safety or disinfection benefit.
Biomaterial compatibility depends on how chlorine chemistry interacts with the material and with any associated biological components. Because oxidizing species can disrupt proteins, lipids, membranes, and cellular function, chlorine conditions must be evaluated rather than assumed to be harmless. Such evaluation helps determine whether a material can support its intended biological role after contact with chlorine-containing environments.
Sterilization conditions should be selected by balancing contamination reduction with the potential effects of chlorine chemistry on biological systems and materials. A suitable evaluation considers whether the treatment preserves required cellular, tissue, or material performance while providing controlled antimicrobial action. This approach helps distinguish useful sterilization from conditions that create excessive exposure and compromise system safety.
A compatibility assessment should examine the response of both biological components and engineered materials to the intended chlorine-containing conditions. Researchers can use the assessment to determine whether proteins, lipids, membranes, cellular function, or overall material performance are adversely affected. The results inform choices about sterilization conditions, protective strategies, and whether the system remains suitable for its application.
Protective systems help limit chlorine-related damage to cells, tissues, laboratory personnel, and engineered biological components. Their design is guided by the distinction between controlled chemistry, which can reduce contamination, and excessive exposure, which can injure tissues or impair biological performance. This makes chlorine exposure relevant not only to disinfection, but also to safer material and system design.
