Cel I aim to transform the way disease is currently detected through innovations in the design of nanoparticle-based biosensors that can be used to detect a number of diseases with global implications. The three most significant challenges facing biosensing are inaccuracy, insensitivity, and low-throughput detection. One technique that is capable of facing these challenges is Surface Enhanced Raman Scattering (SERS) which has demonstrated potential for extreme sensitivity (single molecule detection) and rapid, multiple-analyte detection within complex mixtures. Early stage diagnosis of disease requires the detection of trace amounts of analyte in multi-component biological samples (blood, urine, saliva). It is therefore particularly important for sensors to reach the single-molecule detection limit. Further, the ability to analyse biological samples without separation or other treatment steps is a crucial advantage of SERS.My approach involves the electrotuneable self-assembly of plasmonic nanoparticles at a liquid-liquid interface for SERS detection, overcoming the severe limitations of current sensors (sensitivity, specificity and speed). I will electrochemically control the positioning of the nanoparticles in a precise manner to maximise the Raman signal. Additionally I will utilise shaped nanoparticles, such as stars and ellipsoids, exploiting the enormous Raman enhancements observed at sharp metallic tips to push the sensitivity towards single-molecule detection limits. The ultrasensitive sensing capabilities will be extended to colorectal cancer diagnosis the third most prevalent cancer in the world which effects 1.4 million people per year. Due to the versatility of this system it can be adapted to any disease or virus where the related biomarker is known. This approach will allow me to build a new generation of sensors that will transform single-molecule SERS detection Dziedzina nauki natural sciencesbiological sciencesmicrobiologyvirologynatural scienceschemical sciencesinorganic chemistrytransition metalsnatural sciencesbiological sciencesbiochemistrybiomoleculesproteinsmedical and health sciencesclinical medicineoncologycolorectal cancerengineering and technologynanotechnologynano-materials Program(-y) H2020-EU.1.3. - EXCELLENT SCIENCE - Marie Skłodowska-Curie Actions Main Programme H2020-EU.1.3.2. - Nurturing excellence by means of cross-border and cross-sector mobility Temat(-y) MSCA-IF-2014-EF - Marie Skłodowska-Curie Individual Fellowships (IF-EF) Zaproszenie do składania wniosków H2020-MSCA-IF-2014 Zobacz inne projekty w ramach tego zaproszenia System finansowania MSCA-IF-EF-ST - Standard EF Koordynator IMPERIAL COLLEGE OF SCIENCE TECHNOLOGY AND MEDICINE Wkład UE netto € 183 454,80 Adres SOUTH KENSINGTON CAMPUS EXHIBITION ROAD SW7 2AZ LONDON Zjednoczone Królestwo Zobacz na mapie Region London Inner London — West Westminster Rodzaj działalności Higher or Secondary Education Establishments Linki Kontakt z organizacją Opens in new window Strona internetowa Opens in new window Uczestnictwo w unijnych programach w zakresie badań i innowacji Opens in new window sieć współpracy HORIZON Opens in new window Koszt całkowity € 183 454,80
