When the virus hunters landed in the remote African village of Yambuku in 1976, the nuns warned them to stay back. The sisters had cordoned off the area where they were caring for people dying from a mysterious new disease. In fact, the whole village was sealed off, both by thick jungle and now [...]
Researchers at Karolinska Institutet in Sweden have developed a tiny sensor for detecting pesticides on fruit in just a few minutes. The technique, described as a proof-of-concept in a paper in the journal Advanced Science ("SERS Hotspot Engineering by Aerosol Self-Assembly of Plasmonic Ag Nanoaggregates with Tunable Interparticle Distance"), uses flame-sprayed nanoparticles made from silver to [...]
Scientists from Italy have recently analyzed the effect of the mRNA-based coronavirus disease 2019 (COVID-19) vaccine on the semen quality of adult men. No significant difference in sperm quality and seminal plasma parameters (oxidative stress, inflammation, and electrolyte level) has been observed after vaccination. The study has been published in the journal Andrology. Background Severe [...]
Silver-based nanoparticle presence in everyday items has surged over the past decade. Silver is an efficient antibacterial agent but can harm the environment. A study published in the journal iScience aims to discern the relationship between microbial activity and silver, providing a means for limiting the unintended environmental impact of silver-based nanoparticles Silver – An Effective [...]
Mimicking the human body, specifically the actuators that control muscle movement, is of immense interest around the globe. In recent years, it has led to many innovations to improve robotics, prosthetic limbs and more, but creating these actuators typically involves complex processes, with expensive and hard-to-find materials. Researchers at The University of Texas at [...]
Many cancer treatments are notoriously savage on the body. Drugs often attack both healthy cells and tumor cells, causing a plethora of side effects. Immunotherapies that help the immune system recognize and attack cancer cells are no different. Though they have prolonged the lives of countless patients, they work in only a subset of patients. One study [...]
Scientists have been continually working on creating novel drug delivery systems with increased efficacy and safety. Recently, a new nano-drug delivery system (NDDS) was established based on bio-graphene nanocomposite to treat cervical cancer. This study is available in ACS Applied Bio Materials. Treatment of Cancer and Nanotechnology The World Health Organization has recently stated that [...]
Written by Louis Rosenberg, PhD , CEO and chief scientist of Unanimous AI: Earlier this month, I participated as a panelist at the Digital Orthopedics Conference in San Francisco (DOCSF 2022) where a major theme was to imagine the medical profession in the year 2037. In preparation for the event, a small group of us [...]
In a study published in the journal ACS Applied Materials & Interfaces, a mix of chemistry, nanomaterials, and artificial intelligence (AI) was used to produce a straightforward yet cryptographic anticounterfeiting measure. The Need for Effective Anticounterfeiting Techniques The requirement for robust anti-counterfeit solutions is driving scholarly and corporate research to enhance the authenticity and safety of [...]
The latest study published in the Journal of Cleaner Production focuses on the effective utilization of magnetic nanoparticles for the primary purpose of water treatment to remove toxic wastes such as organic substances, hazardous metal ions, radioisotopes, and other hazardous substances. Why is the Development of Effective Treatment Solutions Necessary? The availability of safe freshwater is [...]
