Strong histamine torsion Raman spectrum enables direct, rapid, and ultrasensitive detection of allergic diseases
Abstract
Summary: Allergic diseases are closely related to degranulation and release of histamine and difficult to diagnose because non-allergic diseases also exhibit the same clinical symptoms as allergy. Here, we report direct, rapid, and ultrasensitive detection of histamine using low-frequency molecular torsion Raman spectroscopy. We show that the low-frequency (3) of histamine reaches 10−8 g/L in water and 10−6 g/L in serum. This scheme thus opens new lines of inquiry regarding the clinical diagnosis of allergic diseases.
