The researchers avoided this trade-off between accuracy and accessibility by developing an alternative antibody testing platform that combines a powerful light-sensing .. DNA origami structure for detecting specific protein The molecules—known as biomarkers—are currently collected in their billions—if not trillions—in order to create a detectable signal of a disease. The new system, which has already been used to detect a protein linked to cystic fibrosis, can compile a detectable signal from just a few biomarkers, and can be done in just a few minutes. The new method involves using DNA origami—a nanoscale techniqu.. Leveraging mRNA Sequences for helping host to have antibody Scientists manipulated a natural cellular process to ramp up levels of two proteins used by the virus to infect other cells, packaged the protein-boosting instructions in nanoparticles and injected them into mice. Within a month, the mice had developed antibodies against the SARS-CoV-2 virus. The technique involves altering specific sequences of messenger RNA, molecules that translate genetic in.. mesoporous nanoparticle for miRNA detection University of Queensland researchers have developed biosensors that use nanoengineered porous gold which more effectively detect early signs of disease, improving patient outcomes. Most diagnostic methods use costly materials and are time-consuming and expensive to run, but Ph.D. candidate Mostafa Masud and research supervisors Professor Yusuke Yamauchi and Dr. MD Shahriar Hossain have developed.. COVID 19 detection through LAMP As reported in the Proceedings of the National Academy of Sciences, the Illinois team used a simpler process to analyze the viral transport media, called LAMP, which bypasses the RNA extraction and purification steps. "LAMP only needs one temperature—65 C—so it is much easier to control," said graduate student Anurup Ganguli, the first author of the study. "Also, LAMP works more robustly than PC.. 3d printed aorta & heart valve have developed a groundbreaking process for multi-material 3-D printing of lifelike models of the heart's aortic valve and the surrounding structures that mimic the exact look and feel of a real patient. Such models can be used in preparation for minimally invasive procedures to improve outcomes in thousands of patients worldwide. The researchers 3-D printed what is called the aortic root, the s.. 70 micrometer size mass producible robot The new robots are about 5 microns thick (a micron is one-millionth of a meter), 40 microns wide and range from 40 to 70 microns in length. Each bot consists of a simple circuit made from silicon photovoltaics—which essentially functions as the torso and brain—and four electrochemical actuators that function as legs. The researchers control the robots by flashing laser pulses at different photov.. LFA for EBOLA detection (논문 읽고 보충하기) The diagnostic tests use the CRISPR-based SHERLOCK assay to detect low levels of virus in patient samples and generate either a fluorescent readout or a result on a paper strip. used on saliva or urine—eliminating the need for blood draws—and can return results in less than an hour. The tests also use a rapid chemical and heat treatment called HUDSON to inactive the virus in patient samples. HUD.. 이전 1 ··· 3 4 5 6 7 8 9 ··· 19 다음
