A team of engineers, including NYU researchers, has developed a simple way to make self-assembled “colloidal diamonds.”. It is reported that colloid is a mixture of particles suspended in the fluid. Different from the solution which is divided into solute and solvent, the colloidal combination does not dissolve, but keeps a relatively independent phase state. < / P > < p > the problem is that it is difficult to mass produce self-assembled “colloidal crystals” based on traditional methods, but the new process can help to make better optical devices. < / P > < p > through the “DNA strand” attached to each particle, when it floats in the liquid, the strand can also be connected in a specific way while maintaining the specific structure of the particle. By changing the attachment position of “DNA strand” on the example, colloidal cube, line and pyramid can also be derived, but the “Diamond State” is still elusive. < / P > < p > to form a diamond, particles need to stick to one place in a staggered form, but they usually do not have such selectivity. Instead, their “DNA strands” stick to anything they can touch. Fortunately, in this new study, researchers from New York University (NYU), the center for scientific research in France (CNRS) and the University of chengjunguan in South Korea have found a new way to form a “Diamond State”. < / P > < p > the knack of the new process begins with a pyramid structure, which is then interlocked with each other in a staggered form. After that, even if the liquid phase is discharged, these crystals can still maintain structural stability, which is particularly important in practical applications. < / P > < p > the research team pointed out that this special arrangement may play an important role in the field of photonics, such as the manufacture of optical waveguides, filters, laser resonators and other components. It is reported that in photonics, light can replace the circuit part. In contrast, traditional computers are still “electronic” devices. The self-assembled “Diamond colloid” with new structure is obviously easier to mass produce, thus accelerating the development of photon technology.
