Abstract

The present invention successfully introduced a new approach to target specific EV subpopulations on the basis of charge-mediated fusion of EVs and CLIPs. By adjusting the surface charge of liposomes through the ratio of positively and negatively charged lipids, the optimal ratio that allows efficient and stable fusion with exosomes was confirmed. A method according to the present invention uses the advantages of a CLIP's high fusion rate, and rapid and broad applicability, and verified excellent sensitivity and selectivity for tumor-derived EV miRNA in a lysis-free manner using droplet-microfluidics. Particularly, the EV-CLIP method enables digital detection of EGFR L858R and T790M mutations without pretreating a sample, and thus can simplify detection processes and prevent EV loss.

Abstract

The present specification relates to a planar coil. The planar coil according to an embodiment may comprise: a substrate; and a conductor layer disposed at at least one of a first surface and a second surface of the substrate and including a plurality of conductor tracks. In an embodiment, the respective conductor tracks may be arranged at different arrangement intervals. In an embodiment, the respective conductor tracks may have different widths. If an AC current is supplied to the planar coil according to embodiments of the present specification, the intensity of a magnetic field formed around the planar coil is increased and the magnetic flux density thereof is enhanced. Accordingly, the performance of devices using electromagnetic induction through the planar coil can be improved.
