| Popis: | Intermolecular forces constrain peptide conformation. However, the role of each intermolecular force in constraining peptide conformation remains poorly understood. In this work, we show that aromatic-aromatic interactions drive peptides into β-sheets, and the hydrophobic effect determines the assembly speed of peptides. By using intermolecular forces to artificially control the assembly of β-sheets, a multi-modal analytical system was developed that allows five readouts and dual qualitative-quantitative analysis, and satisfies both point-of-care testing (POCT) and laboratory-based testing. For Mycoplasma Pneumoniae diagnosis, this system eradicates misdiagnosis (from 30 % to 0 %) and broadens the linear range by three-fold, both of which are critical for guiding therapy. This work not only illustrates exact roles of intermolecular forces in driving the formation of β-sheets, but also provides a guideline for the construction of a multi-modal analytical system for disease diagnosis. |
