Neural Interface

Neural probe is a microstructure which connects neural tissue with external electrical, optical or chemical systems.

In this structure, size, thickness, dimension and impedance are important issues to have the least brain damage during and after implantation.

Micromachining technique has been used in probe production in which probe lies in the gold nanoparticle bath and then a layer of carbon nanotube with 2-micron thickness forms on the electrode body.

Finally, nanoparticles are homogenized by ultrasonic wave and complete the probe structure

Phase 1 approach, in which MEnTs are first injected into the circulatory system, localized into the cerebral tissue using a magnetic field gradient, and then interact with neural tissue and applied magnetic fields to provide non-surgical neural interfacing.

The nanotransducer would use magnetoelectric nanoparticles to establish a bi-directional communication channel with the brain.

Neurons in the brain operate through electrical signals.

The magnetic core of the nanotransducers would convert the neural electrical signals into magnetic ones that would be sent through the skull to the helmet-based transceiver worn by the user.

The helmet transceiver could also send magnetic signals back to the nanotransducers where they would be converted to electrical impulses capable of being processed by the neurons, enabling two-way communication to and from the brain.

Among other accomplishments in Phase 1, were efforts in write technology that achieved targeted and non-invasive delivery of viruses in mice, demonstrating fast magnetic stimulation in mammalian cells; also in viral delivery using magnetic iron oxide nanocrystal clusters of core/shell with high magnetic heating efficiency and magnetothermal multiplexing.

Phase 2, the team aims to advance its work further toward the goal of reaching demonstration in humans in Phase 3.

Among the goals for Phase 3 are to accomplish non-surgical reads, writes with magnetogenetics, and to demonstrate closed-loop brain-to-brain MOANA link in humans.

"Dear Proton supporter,

We're thrilled to announce that Proton Wallet is now available for everyone. Proton Wallet is a safer and simpler way to hold and transact with Bitcoin, empowering you to manage your finances yourself without relying on central authorities like banks or crypto exchanges.

We want to thank you for being one of the first 100,000 users on Proton Wallet Early Access. We have received very positive feedback from the community and have made many improvements to the service over the last year.

Proton Wallet is now ready to bring financial freedom and sovereignty to all. Simply download and install our free apps for Android or iOS and log in using your Proton username and password. For our web app, which also has premium Proton plans, go to https://wallet.proton.me on your browser.

Improvements during Early Access
Wallet welcome banner
Thanks to the feedback and support from early adopters like yourself, we have made the following major improvements to Proton Wallet:

Improved blockchain sync performance by up to 10x on mobile apps
Added replace-by-fee feature so you can speed up transactions
Added MoonPay as another on-ramp partner on the web app
Added address list feature so you can see all your BTC addresses
Support our fight for financial privacy and freedom
Like other Proton services, Proton Wallet is strongly influenced by feedback and financial support from our community. We have no venture capital investors and do not use an advertising business model — we exist to serve you.

In addition to subscribing to our premium Proton plans, you can support us by sending BTC donations to our non-profit Proton Foundation at foundation@proton.me using Bitcoin via Email on Proton Wallet.

Stay secure,
The Proton Wallet team"

fwiw, I've previously used Moonpay too #Good
Running a little behind schedule but CANADA page now live (with only Yukon posts done so far, but it's there!). Live editing the rest of this afternoon until done. :)
