KATY, TX / ACCESS Newswire / July 13, 2026 / Hormones act as invisible signaling messengers regulating nearly all biological activities, playing irreplaceable roles in inflammation, reproductive development, tumor microenvironment research, neuroscience and other core life science fields. However, small-molecule hormones face inherent detection bottlenecks: highly similar chemical structures, lack of dual binding epitopes required for conventional immunoassays, ultra-low concentrations in complex biological matrices, and severe background interference. Long-standing pain points including insufficient sensitivity, poor specificity and cumbersome operation have blocked researchers from obtaining authentic experimental data from precious samples.
