Bioimpedance offers a non-invasive, cost-effective method to detect changes in electrical properties that correlate with DNA concentration levels.
According to the study, measurements around 5 kHz (resistance) and 200 kHz (reactance) provide the most reliable sensitivity for DNA quantification.
The optimal frequency range for measuring DNA concentration using electrical bioimpedance spectroscopy varies depending on the specific experimental conditions and DNA sample. However, generally, exploring a broad frequency range (e.g., from kHz to MHz) is recommended to identify the frequencies at which impedance changes are most sensitive to DNA concentration variations.
Yes, bioimpedance measurements can potentially differentiate between single-stranded (ssDNA) and double-stranded DNA (dsDNA). The electrical properties of ssDNA and dsDNA differ due to variations in their structure and charge distribution. By analyzing the impedance response at different frequencies, researchers can identify characteristic patterns that correlate with the presence of ssDNA or dsDNA.
Key factors affecting the reliability of DNA bioimpedance measurements include:
The use of Electrical Bioimpedance Spectroscopy for DNA quantification represents a significant step forward in molecular diagnostics.
