Graphene quantum dots split Cooper pairs

...
..
Superconducting "Cooper pairs" of electrons have been split to create entangled pairs of electrons in a new device built by physicists in Finland and Russia. The device employs two quantum dots made of graphene. Although other types of quantum dots have been used for this purpose, the latest research suggests that graphene quantum dots should deliver long-lived entangled electron pairs that could be used in quantum computers.

The latest work, carried out by Pertti Hakonen and colleagues at Aalto University in Finland together with Gordey Lesovik of the Landau Institute for Theoretical Physics near Moscow, instead uses quantum dots made from graphene. Graphene should be able to preserve the entanglement of the separated electron pair for longer, thanks to the fact that it consists of a single layer of carbon atoms, which constrains the electrons to move in a straight line and so avoids the emission of electromagnetic radiation that interferes with the spin state.

As expected, looks like our little Graphene concept has been allowing Thermofisher and the extractions of impurities for CDMOs to revolutionize the CDMO market and Ampersand Capital looking to divert customers over to MedPharm CDMO and TriPharm CDMO and they needed New England Peptides ...so when does the tide turn for Avid CDMO shareholders making their voices heard to Ampersand ...to Richard Charpie and ALL of those at Ampersand looking to squeeze CDMO customers to other CDMOs?? A disgrace that they have not updated us on clients and contracts to verify all secured ...and force Oncologie to update all NOW

Graphene Based Materials ready for the next frontier ....just as we enter "The Enlightenment Age Of Disease" and Thermo Fisher requires the knowledge to pull impurities out of the batches ? Hell yes

Introduction
The interest in graphene has been growing rapidly over the past several years. This is primarily driven by its potential as a material with which to manufacture nanoelectric devices â?? although this is far from its only application. Raman spectroscopy is used extensively to characterize graphene, as the material is composed almost entirely of symmetric
2
sp bonded carbon which is represented in great detail in
the Raman spectrum.

Multifunctional hybrid graphene oxide for circulating tumor cell isolation and analysis.

...
...
Recent advancements in nanoscience allow us to design nano-architectures with the capability of targeted CTCs isolation and identification. In the current review, we discuss contribution from different groups on the development of graphene oxide based nanoarchitecture for effective isolation and accurate identification of CTCs from whole blood. In the last few years, using zero-dimensional (0D), two dimensional (2D) and three dimensional (3D) multifunctional hybrid graphene oxide (GO), different types of nanoarchitectures have been designed. These nanoarchitectures represent a highly powerful platform for CTC diagnosis.

Graphene-based Field Effect Transistor (FET) Biosensors

Field effect transistors (FET) apply an electric field to control the electrical activity of a device. Their employment in biosensing applications is as a result of the full electronic detection ability that can be produced on electronic chips. These types of biosensors work by the biorecognition event that occurs between a probe and target biomolecules at the gate of the FET.

During the biorecognition event, the electric charge produced changes in the conductivity of the channel between source and drain. Field effect transistor biosensors are particularly useful for identifying charged biomolecules such as the charged phosphate backbone of DNA. Graphene is a good material for this type of biosensor because it allows for band gap tuning through surface modification and can detect gate voltage change formed from small amounts of single stranded DNA.

Current Assignee
Lockheed Martin Corp

Abstract

A device isolates a substance from blood. The substance includes particles with an effective diameter that is within a range defined by effective diameters of constituents of blood. The device comprises a first sheet of graphene including a first plurality of apertures. The first plurality of apertures are configured to pass objects with an effective diameter less than or equal to the effective diameter of the particles of the substance. The device comprises a second sheet of graphene including a second plurality of apertures. The second plurality of apertures are configured to pass objects with an effective diameter less than the effective diameter of the particles of the substance. The device may be configured to include a conduit system. The device may be configured to operate according to a reversible cycle.
