Influenza Screening: Could a Taste-Based Sensor Play a Role?

Selective methylation of N-acetylneuraminic acid enabled a taste-releasing sensor to distinguish influenza neuraminidase from bacterial enzymes

1

Researchers developed a taste-based influenza screening approach using viral neuraminidase activity to activate a chemically engineered sensor.
2

The sensor design incorporates N-acetylneuraminic acid derivatives linked to thymol, ensuring selectivity for viral neuraminidase.
3

Only the modified α-linked sensor with 4,7-di-O-methyl substitutions demonstrated selectivity for viral neuraminidase over bacterial neuraminidase.

Neuraminidase activity in saliva from influenza-positive patients matched concentrations needed for sensor activation, ranging from 8.9 to 13.4 mU/mL.
5

The sensor strategy offers potential for low-cost, rapid testing at the point of care, pending assessment against patient-reported outcomes.
