Fast Capture of Extracellular Vesicles Enables Precision Cancer Diagnoses

Lipid nanoprobes (blue, green and yellow colored) spontaneously insert into lipid bilayer of three extracellular vesicles. The cargo content of extracellular vesicles includes proteins, DNA and RNA. The lipid nanoprobe-labeled extracellular vesicles are captured onto the surface of a magnetic bead (black, bottom) through interaction with conjugated avidin molecules (red). Exosome isolation and its cargo analysis offers new opportunities for a diverse range of molecular analyses, including mutation detection from blood plasma of cancer patients.

Portable Ebola Test Brings Quicker Diagnosis to Remote Regions


Researchers have created a portable and fast-acting test that can distinguish Ebola infections from other fever-causing infectious diseases such as Lassa fever and malaria in around 30 minutes. Although further testing is required, this could be useful during febrile disease outbreaks.


Precise Engineering of Graphene Could Benefit Lab-on-a-chip Applications


A team of NYU researchers has solved a longstanding puzzle of how to build ultra-sensitive, ultra-small electrochemical sensors with homogenous and predictable properties by discovering how to engineer graphene structure on an atomic level.


Drug Seeks Out Receptors in Sarcoma Cells, Shrinks Tumors


A new compound that targets a receptor within sarcoma cancer cells shrank tumors and hampered their ability to spread in mice and pigs, a study from researchers at the University of Illinois reports.
