Article Synopsis
- This study develops a method to estimate the amount of 1,5-diaminopentane (cadaverine) adsorbed on a microcantilever sensor by analyzing its resonance frequency in relation to known added masses.
- This research builds on earlier work related to an electronic nose designed to assess the freshness of meat and fish by detecting cadaverine levels.
- Through theoretical and experimental analyses, the resonance frequency response to differing cadaverine concentrations was used to create a polynomial model capable of estimating the mass of cadaverine adsorbed on the sensor.
Micro-cantilever sensors are a known reliable tool for gas sensing in industrial applications. We have demonstrated the application of cantilever sensors on the detection of a meat freshness volatile biomarker (cadaverine), for determination of meat and fish precise expiration dates. For achieving correct target selectivity, the cantilevers need to be functionalized with a cadaverine-selective binder, based on a cyclam-derivative.
