Abstract:
A molecular manipulation apparatus for investigating molecules attached on one side to a surface of a sample and on another side to a bead. The apparatus having a radiation system for providing a radiation beam of radiation with a radiation intensity to the sample and the surface of the sample is transmissive for the radiation. The apparatus is provided with a sample holder for holding the sample with its transmissive surface within the beam of radiation. The apparatus has a detector for detecting a position of the beads; and, a computer programmed for calculating a physical property of the molecules as a function of the position of the plurality of beads.
Abstract:
A molecular manipulation system for investigating molecules,having a sample holder constructed to hold a sample comprising a plurality of molecules attached on one side to a surface in the sample holder and on another side attached to a microbead of a plurality of microbeads. The system having; an acoustic wave generator to generate an acoustic wave exerting a force on the microbeads in the sample; anda detector device to detect a response of the plurality of microbeads in the sample on the force exerted by the acoustic wave to investigate the molecules attached to the microbeads.
Abstract:
The present disclosure concerns a method and system for imaging a molecular strand (MS). The method comprises providing a sample volume (SV) comprising the strand (MS); providing an excitation beam (EB) having an excitation focus (EF) in the sample volume (SV); scanning the excitation focus (EF) in the sample volume (SV) along a one dimensional scanning line (SL); trapping an end of the strand (MS) in the sample volume (SV) and extending the strand (MS) along a one-dimensional trapping line (LL) parallel to the scanning line (SL); aligning the trapping line (LL) to coincide with the scanning line (SL) to have the scanning excitation focus (EF) coincide with the strand (MS); and recording the fluorescence response (FR) as a function of a plurality of distinct scanning positions (X0) of the excitation focus (EF) along the scanning line (SL).
