Study provides insight into how nanoparticles interact with biological systems

Personal electronic devices—smartphones, computers, TVs, tablets, screens of all kinds—are a significant and growing source of the world's electronic waste. Many of these products use nanomaterials, but little is known about how these modern materials and their tiny particles interact with the environment and living things.
Now a research team of Northwestern University chemists and colleagues from the National Center for Sustainable Nanotechnology has discovered that when certain coated nanoparticles interact with living organisms it results in new properties that cause the nanoparticles to become sticky. Fragmented lipid coronas form on the particles, causing them to stick together and grow into long kelp-like strands. Nanoparticles with 5-nanometer diameters form long structures that are microns in size in solution. The impact on cells is not known.

Personalis and ClearNote Health Announce Partnership to Advance Epigenomic Technology

Personalis, Inc. | February 05, 2024

Personalis, Inc. a leader in advanced genomics for cancer, and ClearNote Health, Inc., a pioneer in epigenomic technologies, today unveiled an alliance through which Personalis will expand its pharmaceutical service offerings by distributing ClearNote’s cutting-edge epigenomic 5-hydroxymethylcytosine (5hmC) platform. “We have built a unique pharma channel based on our industry-leading tissue and MRD assays and ClearNote Health’s blood-based epigenomic approach is complementary to our offering as it helps our customers deepen their understanding of a patient’s response to immunotherapies,” said Chris Hall, CEO and President of Personalis. “Commercial partnerships such as this broaden our portfolio and are expected to appeal to a wide range of biopharma customers and accelerate our revenue growth.” Echoing this sentiment, Dave Mullarkey, CEO of ClearNote Health, remarked, “Partnering with Personalis presents an excellent opportunity to bring our 5hmC technology to the forefront of cancer research. This alliance is a testament to the synergy between our two companies, enabling us to expand our reach and significantly impact the biopharmaceutical industry. Together, we can accelerate the development of personalized therapies and make a real difference in the lives of patients.” ClearNote Health’s Epigenomics Platform represents a groundbreaking advance in cancer detection, offering real-time insights into disease-specific pathways. By tracking changes in 5hmC levels coupled with artificial intelligence-based analytical methods, the platform can detect cancer earlier, monitor disease progression, understand mechanisms of resistance, and identify promising drug targets and biomarkers. These insights are invaluable for optimizing drug development programs and delivering more effective treatments to patients. The Epigenomics Platform identifies changes in gene activation and gene regulation by labeling specific changes in the 5hmC landscape from plasma-derived cell-free DNA. This rich biological information, as part of clinical trials, enables the monitoring of cancer therapies in real time and contributes to an understanding of drug resistance mechanisms. The partnership marks a pivotal moment in cancer research, leveraging the strengths of both companies to offer unparalleled solutions in the biopharmaceutical industry. About ClearNote Heath, Inc. ClearNote Health is a cancer detection company focused on enabling people at risk for high-mortality cancers to live longer, healthier lives. Utilizing a standard blood draw, the company applies its proprietary epigenomic platform, combining biology and artificial intelligence, to identify DNA-based changes in biology as cancer develops. With lead programs in non-invasive early detection of pancreatic and ovarian cancers in patients at the highest risk for these diseases, ClearNote Health identifies cancers before they progress and when patients are most likely to benefit from treatment. ClearNote Health’s first commercially available test is the Avantect™ Pancreatic Cancer Test, which detects the presence of pancreatic cancer signals in patients at high risk of the disease, including those recently diagnosed with Type 2 diabetes. ClearNote Health is headquartered in San Diego, with additional presence in the San Francisco Bay area and internationally.
