Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view.

Now, researchers at Princeton University and the University of Washington have overcome these obstacles with an ultracompact camera the size of a coarse grain of salt. The new system can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume, the researchers reported in a paper published Nov. 29 in Nature Communications.

Enabled by a joint design of the camera's hardware and computational processing, the system could enable minimally invasive endoscopy with medical robots to diagnose and treat diseases, and improve imaging for other robots with size and weight constraints. Arrays of thousands of such cameras could be used for full-scene sensing, turning surfaces into cameras.

The system relies on a technology called a metasurface, which is studded with 1.6 million cylindrical posts and can be produced much like a computer chip. Credit: Princeton University

New Virus-Mimicking Nanoparticles for Efficient mRNA Delivery into Cells
Reviewed by Laura Thomson
December 1, 2021

https://www.azonano.com/news.aspx?newsID=38280
Nanoengineers at the University of California San Diego have developed a new and potentially more effective way to deliver messenger RNA (mRNA) into cells. Their approach involves packing mRNA inside nanoparticles that mimic the flu virus-;a naturally efficient vehicle for delivering genetic material such as RNA inside cells.

How Nanometrology could be the Key to Next-Generation X-Ray Mirrors
By Marzia Khan
December 3, 2021

https://www.azonano.com/article.aspx?ArticleID=5899
X-ray mirrors which can be made of polished glass ceramics, are given a coat of metal to produce an X-ray reflection. Smooth metallic surfaces like this can reflect X-rays at shallow angles, which may be efficient for high-density metals such as gold, platinum, and iridium.

Nanotechnology for genome editing in multiple muscles simultaneously

by Kyoto University
https://phys.org/news/2021-12-nanotechn ... ously.html
Many intractable diseases are the result of a genetic mutation. Genome editing technology promises to correct the mutation and thus new treatments for patients. However, getting the technology to the cells that need the correction remains a major challenge. A new study led by CiRA Junior Associate Professor Akitsu Hotta and in collaboration with Takeda Pharmaceutical Company Limited as part of the T-CiRA Joint Research Program reports how lipid nanoparticles provide an effective means for the delivery to treat Duchenne muscular dystrophy (DMD) in mice.

Last year's Nobel Prize for Chemistry to the discoverers of CRISPR-Cas9 cemented the impact of genome editing technology. While CRISPR-Cas9 can be applied to agriculture and livestock for more nutritious food and robust crops, most media attention is on its medical potential. DMD is just one of the many diseases that researchers foresee a treatment using CRISPR-Cas9.
