3d printing embryoid body Depending on the signals sent by their adjacent cells, these divided cells are then developed or differentiated into specific tissues or organs. One common approach scientists adopt when differentiating stem cells is by using chemical stimulators. While this method is very efficient to make one single type of cells, it lacks the ability to reproduce the complexity of living organisms, where seve..
new biomarker: enzyme in the gut Enzymes used by bacteria to break down mucus in the gut could provide a useful biomarker for intestinal diseases Researchers at the University of Birmingham and Newcastle University have successfully identified and characterized one of the key enzymes involved in this process. They demonstrated how the enzyme enables bacteria to break down and feed off sugars in the layers of mucus lining the gu..
Raman activated droplet sorting The mining of useful enzymes and microbial cells that produce them has dated back nearly a century. However, such endeavors can be very slow and difficult due to the tiny size of microbes—1000 times smaller than a human cell. Moreover, most of the microbial cells cannot be readily cultured—for this reason, microbiologists call them "biological dark matter." "This is a flow-mode Raman-activated C..
pressure sensitive nano particel *** When nanocellulose is combined with various types of metal nanoparticles, materials are formed with many new and exciting properties. They may be antibacterial, change color under pressure, or convert light to heat. The research group, led by Daniel Aili, has used a biosynthetic nanocellulose produced by bacteria and originally developed for wound care. The scientists have subsequently decorated..
2D 물질을 이용한 도파민 센서 A supersensitive dopamine detector can help in the early diagnosis of several disorders that result in too much or too little dopamine Dopamine is an important neurotransmitter that can be used to diagnose disorders such as Parkinson's disease, Alzheimer's disease and schizophrenia. Their work shows that by adding a small amount of manganese to a two-dimensional layered material called molybdenu..
personalized treatment를 위한 smart watch-drug concentration sensor Engineers at the UCLA Samueli School of Engineering and their colleagues at Stanford School of Medicine have demonstrated that drug levels inside the body can be tracked in real time using a custom smartwatch that analyzes the chemicals found in sweat. In general, medications are prescribed with a 'one-size-fits-all' approach—drugs are designed and prescribed based on statistical averages of the..
cell membrane capacitance 를 이용하여 암세포 감지하기 Separation and characterization of cancer cells are essential for early diagnosis of peritoneal metastasis. However, due to the low content of cancer cells in patients' peritoneal lavages, traditional detection methods lack sensitivity and cannot satisfy clinical demand. jointly proposed an optically induced electrokinetics (OEK) microfluidic method for label-free separation and characterization..
세포 스트레스로 인한 리보솜 충돌에 따른 cell fate When cells experience a high level of stress—for example, when they are exposed to too much UV light—ribosomes inside the cell collide and get into traffic jams. Now, Johns Hopkins scientists have found a protein that recognizes this traffic problem and pushes the cell down a path toward cell suicide. Molecular biologist Rachel Green, Ph.D., and her team have long been studying how cells recogni..
