摘要:
A method an system is disclosed for the detection and/or allocation of at least one point mutation in target DNA and/or RNA duplexes. The method comprises obtaining a functionalized surface which is coated with probe DNA and/or RNA whereto target DNA and/or RNA duplexes are attached, contacting said functionalized surface to an electrolytic solution having a neutral pH in a flow cell and measuring a first impedance value within said electrolytic solution, and then adding a chemical to the electrolytic solution which is able to achieve denaturation of the target DNA and/or RNA. The method further comprises measuring a second impedance value within the flow cell after completion of the denaturation of the DNA and/or RNA target, and then obtaining a value representative for the impact of the chemical on the impedance of the electrolytic solution. The amount and/or allocation of point mutation(s) within the target DNA and/or RNA is then determined by calculating the denaturation-time constant based on the difference between the first and second impedance value and taking into account the impact of the chemical by third impedance value.

A method an system is disclosed for characterising DNA and/or RNA duplexes. The biosensing device comprises a heating element using a power and being suitable for providing thermal denaturation of target DNA and/or RNA bioparticles, a sample holder adapted for receiving a biocompatible substrate having a functionalized surface which is coated with probe DNA and/or RNA whereto target DNA and/or RNA duplexes can be attached, the sample holder further being adapted for exposing the biocompatible substrate at one side to the heating element, a first temperature sensing element for sensing a temperature at the side where the biocompatible substrate can be exposed to the heating element and a second temperature sensing element for sensing a temperature at the side opposite thereto with respect to the biocompatible substrate. The device also comprises a processing means programmed for calculating at least one heat transfer resistivity value based on temperature values obtained with the first temperature sensing element and the second temperature sensing element and the power for the heating element, for deriving a characteristic of the target DNA and/or RNA bioparticles from said heat transfer resistivity value.
