Molybdenum disulfide (MoS 2) has recently garnered attention among materials science researchers owing to its ability to form two-dimensional nanosheets like graphene. The nanosheets are created by ...

DNA origami suggests route to reusable, multifunctional biosensors Using an approach called DNA origami, scientists have developed a technique that could lead to cheaper, reusable biomarker sensors ...

A new microfluidic chip simplifies detecting and quantifying DNA by analyzing electrical impedance signals that vary based on DNA flowing across a biosensor inside the chip. The proof-of-concept ...

The biosensor checks for genetically modified traits using only a quarter-inch diameter pinch of leaf extract. Other ...

Creating new technologically advanced sensors, scientists have engineered bacteria that detect the presence of tumor DNA in live organisms. Their innovation could pave the way to new biosensors ...

In a study reported in the online edition of Science on Aug. 10, 2023, a group of synthetic biologists from the University of California (UC) San Diego and clinicians from Australia have engineered ...

The sensor uses a DNA origami scaffold, which consists of two arms connected by a molecular “hinge.” Each arm is tagged with a fluorescent dye, and the distance between the tags is recorded by means ...

Colorectal cancer (CRC) remains the fourth leading cause of cancer death worldwide, and while the introduction of widespread screening has reduced mortality, current screening techniques have their ...

Mohit Verma’s team at Purdue University has added a portable, paper-based biosensor for recognizing genetically modified (GM) corn and soybeans to its ever-expanding toolset.

A coarse-grained model of the DNA origami lilypad used in the study. The tails hanging down indicate where redox reporters are located. For scale, the diameter of the disk is approximately 80 nm.
