Biosensors
Innovative sensor can screen toxic drugs, help develop biomaterials
Researchers used glass tubing and off-the-shelf electronics to create an inexpensive sensor that can weigh microgram-sized biological samples in fluids
Researchers create unique DNA biosensor for early disease detection
The researchers developed an ultrasensitive, electrochemical DNA biosensor based on “urchin-like” carbon nanotube-gold nanoparticle (CNT-AuNP) nanoclusters that represents a promising signal amplification strategy for DNA detection and diagnostic applications
Ultra-precision nano-sensor could detect iron disorders
Test could lead to earlier, more accurate disease diagnosis
Crumpled graphene can detect DNA without amplification
Researchers have found that crumpling graphene makes it more than 10,000 times more sensitive to DNA by creating electrical ‘hotspots’
Seeking simpler tests for viruses
The coronavirus pandemic highlights the importance of testing for viruses; a simple physical procedure might make it easier, cheaper and quicker
Diagnostic biosensor quickly detects SARS-CoV-2 from swabs
Researchers have developed a field-effect transistor-based biosensor that detects SARS-CoV-2 in nasopharyngeal swabs from patients with COVID-19, in less than one minute
