These diode-like nanofluidic devices can be used to switch the ionic flow on and off based on the polarity of the applied electric field, much like a diode in solid-state electronics. For use in molecular biology, medicine, and chemistry, nanofluidic devices have been developed.
The separation and measurement of fluids containing nanoparticles for drug delivery, gene therapy, and nanoparticle toxicology on a micro-total-analysis system are the principal applications for nanofluidic devices. Ionic transport is corrected by using nanofluidic diodes.
In electronic circuits, a diode restricts the passage of current to one direction. The similar purpose of limiting the ionic flow in one direction is served by a nanofluidic diode.
The study, manipulation, and control of a few molecules or tiny amounts of fluids, frequently contained in a channel with nanoscale 1-100 nm dimensions, are the topics covered by nanofluidics.Nanoparticles that are designed to interact with cells and tissues and perform extremely particular jobs are known as nanodevices.
The imaging devices are the most well-known nanodevices. Small cameras can be found in medications that are taken orally. Examples include quantum well optoelectronic devices including lasers and detectors, heterojunction bipolar transistors, resonant tunnelling diodes, high electron mobility transistors, and transistors.
The Global nanofluidic diodes market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Numerous significant applications, including sensing, electronics, and energy conversion, may benefit from using nanofluidic diodes. It is technically difficult to produce regulated nanopores for nanofluidic diodes, though. In this work, a highly programmable covalent organic framework (COF) is used to create a nanofluidic diode.
A hybrid-bilayer COF exhibits amazing diode behaviour through molecular simulation, although its individual single-layer COF components do not. The asymmetric electrostatic potential across the COF nanopore is thought to be the cause of the rectification effect of ion current in the hybrid-bilayer COF.
Additionally, the presence of counterions is observed to lower the entry barrier and promote ion transport in the hybrid-bilayer COF, revealing a synergistic effect of counterions.
By adjusting the salt content, layer number, interlayer spacing, and slippage, the performance of the hybrid-bilayer COF as a nanofluidic diode is thoroughly examined. This simulation proof-of-concept study shows that the hybrid-bilayer COF can function as a nanofluidic diode, and the result may encourage the creation of novel nanofluidic platforms.
