Point-of-care biosensor for rapid and accurate sepsis diagnosis

Thu, 04/12/2018 - 16:08
Sepsis is the body's extreme response to an infection. It is life-threatening condition in which bacteria or fungi multiply in a patient's blood - often too fast for antibiotics to help. Without timely treatment, sepsis can rapidly cause tissue damage, organ failure, and death. A critical unmet need in combating sepsis is the lack of accurate early biomarkers that can alert clinicians to a potential life-threatening situation and allow them to take preventative action. In a new study, researchers report the development of a point-of-care platform for rapid sepsis detection, called IBS (integrated biosensor for sepsis).

Researchers engineer new pathways for self-assembled nanostructures

Wed, 04/11/2018 - 19:28
Self-assembly is driven mainly by the system's desire to minimize its energy and achieve equilibrium, but kinetic effects can also play a strong role. Typically, these effects are viewed as complications to be overcome, but a collaboration of researchers has recently shown that these effects can be exploited to engineer a nanostructure in a polymer thin film.
