The new sensor is based on a<strong> modular, Lego-like structure<\/strong> that can be easily adapted to detect a variety of molecular targets.<\/p>\n<p>At the core of the sensor is a genetically engineered protein that combines three distinct functions in a single sequence. One segment acts as the detection target, built using fragments of the Spike protein. The central portion, inspired by the human ACE2 receptor, is designed to bind to the viral protein if it is present. The third segment contains <strong>green fluorescent protein<\/strong> (GFP), which functions like a light bulb\u2014emitting a fluorescent signal upon contact with the virus, allowing for <strong>fast and accurate detection<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\" wp-image-31212 aligncenter\" src=\"https:\/\/www-test.unipi.it\/wp-content\/uploads\/virusjpg.jpg\" alt=\"\" width=\"662\" height=\"441\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>\u201cThe biosensor was created using both traditional recombinant protein engineering and innovative technologies such as <strong>click chemistry<\/strong>,\u201d explains <strong>Eleonora Da Pozzo<\/strong> from the University of Pisa. \u201cThis interdisciplinary approach enabled us to develop a sensor with extremely high sensitivity, capable of detecting sub-nanomolar concentrations of viral protein.\u201d<\/p>\n<p>\u201cWhat truly sets this prototype apart is its <strong>modularity<\/strong>,\u201d adds <strong>Giorgia Brancolini<\/strong> from CNR-Nano. \u201cBy combining experimental research with <strong>molecular modeling<\/strong> and <strong>computer simulations<\/strong>, we were able to fine-tune each component and design a flexible, reprogrammable architecture. By altering specific sequences, the sensor can be adapted to identify <strong>other viruses or biomolecules<\/strong>, paving the way for new, customizable diagnostic tools.\u201d<\/p>\n<p>To protect the innovation and support its potential applications, a <strong>national patent application<\/strong> has been filed: Development of a FRET sensor for coronavirus detection (Application No.
