Cover Story: Intracellular bacterial pathogens can evade immune defenses by residing within host immune cells, such as macrophages, creating infection reservoirs that hinder treatment. Changes in macrophage cell surface glycosylation during infection present a potential detection strategy, though glycan diversity complicates profiling. A boronic acid-based pH-responsive polymer sensor array was created to detect bacterial infections in macrophages by identifying distinct glycosylation signatures. This sensor rapidly differentiates between bacterial species within minutes, offering a new tool for diagnostic and screening applications. View this paper
