Nanoscale analysis with DNA-graphene origami

In a recently published study in Advanced Materials Interfaces, INL researchers have developed a new sensor that merges DNA origami with graphene to achieve unique accuracy in detecting molecular motion. Nieder’s group at INL, together with Alpuim’s group (INL) and Thorsten-Lars Schmidt  (Kent State University), developed this innovative sensor that could have significant potential for applications in medicine and environmental monitoring. The sensor combines DNA origami structures and a graphene layer functionalised to interact with fluorescent markers. These markers emit light, and their fluorescence behaviour – specifically its duration – changes based on their proximity to the graphene. By applying electrical signals, researchers can control this distance, enabling them to track movements as small as two nanometres. “The novelty here is that we can actually gate the graphene and sense the effects of this electrostatic approach in the fluorescent behaviour of the fluorophores,” explains João Azevedo, first author of the study. The team used Fluorescence Lifetime Imaging Microscopy (FLIM), a technique that measures the time fluorescence lasts, to achieve this high-resolution sensing. Unlike traditional fluorescence intensity methods, FLIM is less affected by photobleaching, a process where fluorescent markers lose their ability to emit light after prolonged exposure. By focusing on lifetime […]

Mission NERD Brings Science to Life at Eduardo Pondal

This week, the Eduardo Pondal School in Vigo became a hub of scientific discovery as it hosted Mission NERD (Nanotechnology Education and Research Demonstrations), an initiative led by the International Iberian Nanotechnology Laboratory (INL). A group of 80 enthusiastic children participated in this unique program, designed to bridge the gap between science and society while igniting creativity and curiosity in the next generation.

Nanodiamonds bring new hope for Parkinson’s research with advanced neuronal sensing

Researchers at INL – International Iberian Nanotechnology Laboratory from Nieder research group, in collaboration with ICVS and iBiMED, are pioneering the use of functionalised nanodiamonds. This innovative approach offers a highly precise method to monitor neuronal activity at the cellular level, advancing our understanding of Parkinson’s disease. This breakthrough, published in ACS Applied Materials & Interfaces, could help understand the complex biological shifts occurring in the brains of patients suffering from neurodegenerative diseases, potentially leading to earlier diagnosis and personalised treatment. Parkinson’s disease, which affects over 10 million people worldwide, is characterised by the gradual loss of dopamine-producing neurons in the brain. This leads to motor symptoms such as tremors, difficulty with balance, and slowed movement. Studying these neurons at the single-cell level is crucial to understanding the disease’s progression. However, existing methods for observing neuronal activity, such as microelectrode arrays and patch-clamp techniques, have significant limitations, including poor spatial resolution and invasiveness. A promising alternative comes from the world of nanotechnology. Nanodiamonds are tiny diamond particles, just a few nanometres in size, known for their exceptional stability and biocompatibility. When these nanodiamonds contain special defects called nitrogen-vacancy centres, they gain unique optical and magnetic properties, making them a powerful […]
