IAM: Even biometrics can be hacked

Of all the methods used in identity and access management (IAM), biometrics is arguably the oldest: it has been around long before IAM was a “thing”. Humans are naturally optimized for recognizing fellow humans’ faces, voices and other biometric features. However, even biometric recognition between humans is less than perfect, as countless cases of successful impersonators and impostors…

Conductive hydrogel could replace brain tissue

Due to their tissue-like mechanical properties, hydrogels are being increasingly used for biomedical applications; a well-known example are soft contact lenses. These gel-like polymers consist of 90 percent water, are elastic and particularly biocompatible. Hydrogels that are also electrically conductive allow additional fields of application, for example in the transmission of electrical signals…

Biosensor chip detects genetic mutation with higher sensitivity

A team led by the University of California San Diego has developed a chip that can detect a type of genetic mutation known as a single nucleotide polymorphism (SNP) and send the results in real time to a smartphone, computer, or other electronic device. The chip is at least 1,000 times more sensitive at detecting an SNP than current technology. The advance could lead to cheaper, faster and…

Easy printing of biosensors made of graphene

Cell-based biosensors can simulate the effect of various substances, such as drugs, on the human body in the laboratory. Depending on the measuring principle, though, producing them can be expensive. As a result, they are often not used. Cost factors for sensors that perform measurements electrically are the expensive electrode material and complex production. Fraunhofer scientists are now…

Solid-State nanopores unravel twisted DNA mystery

Cancer thrives when mutated cells undergo frequent division. Most anti-cancer drugs work by inserting themselves in between the DNA base pairs that encode our genetic information. This process is known as intercalation, and it can result in subtle changes to the DNA molecule’s geometric shape or tertiary structure. These structural changes interfere with the DNA’s transcription and a cell’s…
