Nanopore sensors detect single molecules by analyzing changes in pore conductance. This technology enables real-time identification and quantification of targets like DNA and proteins for biomedical applications.
Area of Science:
- Biophysics
- Nanotechnology
- Molecular Biology
Background:
- Nanopores, molecular-scale pores, can be engineered from proteins or fabricated using nanotechnology.
- Functionalized nanopores detect target molecules via characteristic changes in pore conductance, acting as molecular fingerprints.
- Nanopore sensors are versatile tools for biomedical detection, identifying targets from ions to DNA.
Purpose of the Study:
- To investigate the folding and unfolding mechanisms of a single G-quadruplex DNA aptamer using nanopore technology.
- To develop a portable and durable molecular device for real-time detection by integrating a protein pore sensor with a solidified lipid membrane.
Main Methods:
- Utilized nanopore sensing to analyze the conformational dynamics of a single G-quadruplex DNA aptamer.
- Engineered a portable device combining a protein pore sensor and a solidified lipid membrane for integrated sensing.
Main Results:

Detection of Black Holes
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...
