The need to a robust and effective methods for secure data transferring makes the more credible. Two disciplines for data encryption presented in this paper: machine learning and deoxyribonucleic acid (DNA) to achieve the above goal and following common goals: prevent unauthorized access and eavesdropper. They used as powerful tool in cryptography. This paper grounded first on a two modified Hebbian neural network (MHNN) as a machine learning tool for message encryption in an unsupervised method. These two modified Hebbian neural nets classified as a: learning neural net (LNN) for generating optimal key ciphering and ciphering neural net CNN) for coding the plaintext using the LNN keys. The second granulation using DNA nucleated to increase data confusion and compression. Exploiting the DNA computing operations to upgrade data transmission security over the open nets. The results approved that the method is effective in protect the transferring data in a secure manner in less time

“…This is the very first example of an all-photonic molecular logic platform operative in solid-state responding to the intrinsic parameters of the pulsed laser excitation source, such as the frequency and the pulse-width, along with the temperature as the physical stimulus, although other reports are known of systems actuated by chemical inputs. [42,43] The rationally designed nanoplatform consisting of monodispersed Yb 3+ /Er 3+doped Sr 2 YF 7 @Sr 2 YF 7 core@shell NPs synthesized through the thermal decomposition method whose luminescence acts in response to the parameters of the pulsed excitation source. The Yb 3+ /Er 3+ -co-doped core@shell platform is reconfigurable depending on the selected logic output and performs the photonic concatenation of a two-NAND logic gates.…”

Computers and computing systems are getting an increasingly essential role in society, as revealed by the current emergence of Artificial Intelligence. The further increase in computer systems and digitalization of society will certainly demand innovative computing systems with higher processing speeds at low energetic and capital costs. Remarkable developments in the last five years have been reported for quantum computing; nevertheless, photonic and molecular computing has also been evolving with the potential of reaching the maximum possible miniaturization by using molecules as building blocks for basilar logic systems. One of the main challenges for molecular logic is the logical connection between molecular elements, called concatenation. Until now, concatenation of molecular logic gates has been exclusively reported using chemical species, with obvious practical limitations. In this work, the first photonic concatenation of a NAND with an AND molecular logic gate is presented. The logic system is implemented on nanoplatforms of Yb3+/Er3+ core@shell Sr2YF7 nanocrystals that are used to define combinatory logic gates and temperature‐reconfigurable logic systems. The results show that upconverting nanocrystals are promising platforms for the development of solid‐state molecular logic devices. These devices can reproduce the logical operations that are currently implemented in electronic devices.

“…The high capacity and chemical stability of DNA make it an ideal platform for data storage. This innovative technique was first proposed in 1988 [ 11 ]. A further step was investigated by Goldman and colleagues [ 12 ], they stored ASCII text, JPEG, and MP3 file formats in DNA and then shipped the DNA worldwide under standard conditions.…”

In the past few decades, the field of DNA origami-based micro/nanotechnology has developed dramatically and spawned attention increasingly, as its high integrality, rigid structure, and excellent resistance ability to enzyme digestion. Many two-dimensional and three-dimensional DNA nanostructures coordinated with optical, chemical, or magnetic triggers have been designed and assembled, extensively used as versatile templates for molecular robots, nanosensors, and intracellular drug delivery. The magnetic field has been widely regarded as an ideal driving and operating system for micro/nanomaterials, as it does not require high-intensity lasers like light control, nor does it need to change the chemical composition similar to chemical activation. Herein, we review the recent achievements in the induction and actuation of DNA origami-based nanodevices that respond to magnetic fields. These magnetic actuation-based DNA nanodevices were regularly combined with magnetic beads or gold nanoparticles and applied to generate single-stranded scaffolds, assemble various DNA nanostructures, and purify specific DNA nanostructures. Moreover, they also produced artificial magnetism or moved regularly driven by external magnetic fields to explain deeper scientific issues.
