In an article recently published in the journal Applied Surface Science, the researchers synthesized green fluorescent carbon dots (G-CDs) from 3,5-diaminobenzoic acid and citric acid. The as-prepared G-CDs were used to target the nucleolus and to carry exogenous DNA molecules into the nucleolus. In addition, the carbon dots (CDs) were used to monitor the levels [...]
Doxorubicin (DOX) is a powerful anti-cancer medication, and efforts have been made to design nanostructures for delivering it to cancerous cells. The nanostructures increase the cytotoxic effects of DOX on cancerous cells, while reducing the negative effects on healthy cells. In a research paper published in the journal Scientific Reports, layered double hydroxide (LDH) nanostructures were developed to [...]
A team of Brown University researchers has developed a new responsive material that is able to release encapsulated cargo only when pathogenic bacteria are present. The material could be used to make wound dressings that respond quickly to burgeoning infections, but only deliver medication on demand. The development is particularly relevant in the face [...]
Novel three-drug regimen used to manage life-threatening developments. In April 2021, a 42-year-old man reached out to Brian Hill, MD, PhD, for a second opinion after being diagnosed with hairy cell leukemia following a bone marrow biopsy at a healthcare facility in northwest Ohio. “At the time of diagnosis, he was getting easily fatigued and [...]
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 [...]
