Embodiment Construction

[0044] Embodiments of the invention are based on nanostructures comprising so-called nanowires. For the purposes of this application, nanowires will be construed as having nanometer dimensions in their width and diameter and generally having an elongated shape, which imparts one-dimensional properties. Such structures are also commonly referred to as nanowhiskers, nanorods, nanotubes, one-dimensional nanoelements, and the like. The basic process of forming nanowires on a substrate by particle-assisted growth or the so-called VLS (vapor-liquid-solid) mechanism described in US Patent No. 7,335,908 and the different types of chemical beam epitaxy and vapor phase epitaxy methods are well known . However, the invention is neither limited to such nanowires nor to VLS processes. Other suitable methods for growing nanowires are known in the art and are shown, for example, in International Application No. WO 2007 / 104781. It follows that nanowires can be grown without using particles...

Abstract

The invention relates to a nanowire device for manipulating charged molecules. The nanowire device comprises a tubular nanowire with a through-going channel; a plurality of individually addressable wrap gate electrodes arranged around the tubular nanowire with a spacing between each two adjacent wrap gate electrodes; and means for connecting the wrap gate electrodes to a voltage source. The invention further relates to a nanowire system comprising at least one of the nanowire device, and to a method for manipulating the charged molecules within a through-going channel of the tubular nanowire.

Description

technical field [0001] The invention relates to the introduction of molecules into cells, and in particular by using a tubular nanowire according to the preamble of the independent claim as introduction device. Background technique [0002] It is well known that cancer is a heterogeneous disease and that a patient's tumor comprises many different cell populations. Thus, little is known about how cells with different phenotypes / phenotypes respond to chemotherapy. This makes it difficult to predict the clinical progression of the tumor and makes existing treatments suboptimal / suboptimal. [0003] A great challenge in biology is the real-time observation of processes at the single-cell level, where fundamental processes related to life can be observed and important insights / insights into underlying heterogeneity within cells can be obtained. What is currently missing in the field is the combination of two capabilities: first, to individually perturb and probe large numbers of...
