Nov 02, 2023 (Nanowerk News) Nanoengineers have created a quasicrystal—a scientifically intriguing and technologically promising material structure—from nanoparticles using DNA, the molecule that encodes life. Key Takeaways Quasicrystals, different from ordinary crystals, possess unique properties like altered heat and light absorption and special electronic behaviors. The team employed DNA strands to instructively bind particles, creating…

Nov 02, 2023 (Nanowerk Spotlight) The rapid detection of disease biomarkers is critical for early diagnosis and timely treatment of illnesses. However, conventional methods like immunoassays require labelling and long processing times, making point-of-care testing difficult. An emerging alternative is nanomaterial-based electronic biosensors. These devices can directly convert biological signals into measurable electrical outputs compatible…
