Hur DNA‑3D‑skrivare kan omvandla mikrochipdesign

A team of scientists from multiple prestigious learning institutions just unlocked the key to nano-scale fabrication. Their novel approach utilizes a specially built DNA 3D printer. This completely new approach to fabricating targeted 3D nanoscale structures relies on the predictability and self-assembly characteristics that DNA possesses. Interestingly, the technology utilizes modular DNA structures that can link together to form larger architectures. These structures can help to drive advanced technologies such as neuromorphic computing, thermal decoupling, and future microchip design. Here’s what you need to know.

Varför nanoskala‑tillverkning är viktigt

The age of small-scale fabrication has led to major technological breakthroughs. Miniaturization of core computational components has allowed engineers to create microelectronics that would seem like sci-fi only 5 years prior.  However, even advanced chips that rely on photolithography to laser etch stencils are limited in their ability to be miniaturized.
Technologies such as additive manufacturing have helped to push small-scale fabrication methods further, but they have been bottlenecked recently. As nano-fabrication becomes the next stage in miniaturization, these technologies have fallen short due to the unique requirements needed to create nano-sized structures. Notably, nanostructures are ideal for high-tech science applications as they provide superior bond strength, structural support, and can assist in the transport of heat or electricity if needed.

Utmaningarna med att skriva ut mikroelektronik

The problem with using 3D printers to create nanoscale projects is that their sheer size makes it impossible to ensure that they will retain their structure. This problem becomes even more relevant when dealing with complex three-dimensional structures.

Hur DNA‑3D‑skrivaren fungerar

Recognizing these limitations and the need to explore the nano-fabrication process further, a team of engineers from Columbia and Brookhaven National Laboratories released the “Encoding hierarchical 3D architecture through the inverse design of programmable bonds” study¹.

This paper explores the potential of utilizing DNA as a 3D printing material. DNA has some unique qualities that make it ideally suited for this task. For one, it self-assembles due to natural reactions. This bio-organization means that these structures will form once printed without additional steps.

Varför DNA är idealiskt för nano‑utskrift

The engineers predicted that DNA would be the perfect solution to nano-fabrication for several reasons. For one, it can only fold in certain ways based on the four nucleic acids. This predictability makes it easier to create sturdy structures that don’t require extra steps to assemble. Additionally, they make the structure mechanically robust and durable.

Voxlar: DNA‑byggstenarna

The scientist decided that an eight-sided octahedral shape called a voxel would be the best approach. Voxels form strong bonds at exact locations at the corners of each unit. Additionally, they can be grouped predictably to create a larger structure.
According to researchers, one of the most complicated steps of the entire experiment was determining how to set up the starting sequence for the voxels to create the intended structures. DNA structure can include billions of points. Thankfully, the voxel’s unique characteristics ensured that an inverse structural design was possible.

MOSES: DNA‑origami‑designverktyget

The engineers called their approach to nano-fabrication a bit like “DNA origami.” This name refers to how the DNA is set up to fold in certain ways based on the coding directions provided by the engineers. To accomplish this task, the team needed to create a computational model.

They developed the system called Mapping Of Structurally Encoded Assembly (MOSES) to act as a design studio for their creations. The software allows scientists to arbitrarily define a 3D hierarchically ordered lattice and verify its capabilities before printing.

Engineers can even develop nano designs that have cargo within them. This cargo can be used to ensure that the targeted hierarchically organized structure remains durable. Also, the computer model was crucial in helping engineers fine-tune their DNA structural design, allowing engineers to test different DNA structures and materials.

Hur DNA‑självmontering fungerar

Testning av DNA‑3D‑skrivaren

The engineers tested their work at the Columbia and Brookhaven National Laboratories. Specifically, the team utilized synchrotron-based X-rays and electron microscopes to examine the DNA structures and stress test their capabilities.
As part of the testing phase, the team printed multiple items. The first prints included low-dimensional elements. The next designs included helical motifs, a face-centred perovskite crystal shape, and a distributed Bragg reflector. Notably, these shapes provided unique characteristics built into their design.

Vad DNA‑3D‑skrivarens tester visade

The results showed that the nanostructures matched the computer model predictions exactly. They self-assembled as predicted and demonstrated the added resilience compared to previous methods of small-scale fabrications. Additionally, the engineers noted that using different materials provided different characteristics to the structure.
For example, the introduction of gold nanoparticles provided some of the tested structures with desirable optical properties for laser computing and more. The same concept could be used to create materials that are super heat-resistant or can transfer electrical pulses seamlessly.
