The project will involve the synthesis of advanced upconversion nanoparticles and their characterisation aimed at assessing their suitability as dual-mode (optical and MRI) imaging materials for cancer tissues. Upconversion nanoparticles are inorganic nanoparticles that are capable of emitting visible light under near-infrared laser excitation allowing us to image deeper into the tissues with less interference compared to other light-based imaging techniques.
<p style="margin-bottom:11px">The synthesis of upconversion nanoparticle (UCNP) based systems and their surface functionalisation with selected Affimers/antibodies for dual-mode imaging applicable to cancer tissues is the overall objective of this project. In this project we propose to develop different types of UCNPs doped with different rare earth ion sensitizer and activator combinations (Yb3+, Er3+, Tm3+ and Ho3+) will be developed. The factors such as type of precursors, surfactants other preparative conditions are varied to obtain particles having different shapes, phase and high photoluminescence intensity. Surface modification with various polymers and other suitable methods (such as coating with silica) followed by conjugation of Affimers will allow targeted imaging. Development of particle systems which suits dual modal imaging (Optical/magnetic) applications seek importance. The cytotoxicity analysis of particles of interest will be carried out using MTT assay, NRU assay or comet assay, which could be assessed before preclinical trials.</p> <p>Advanced structural characterisation of the UCNP systems using electron microscopy, X-ray diffraction, and laser spectroscopy will be undertaken prior to their use in imaging experiments. The imaging experiments will be carried out in collaboration with Leeds Teaching Hospitals and the School of Medicine and Health. In the dual model imaging, the student has to develop the functionally modified particle with optically and magnetically active centres in order to acquire optical and MRI image. </p>
<p>Formal applications for research degree study should be made online through the <a href="https://www.leeds.ac.uk/research-applying/doc/applying-research-degrees">University's website</a>.

Potential applicants are strongly encouraged to contact the supervisors for an informal discussion before making a formal application. We also advise that you apply at the earliest opportunity as the application and selection process may close early, should we receive a sufficient number of applications or that a suitable candidate is appointed.</p> <p>Please note that you must provide the following documents at the point you submit your application:</p> <ul> <li>Full Transcripts of all degree study or if in final year of study, full transcripts to date</li> <li>Personal Statement outlining your interest in the project</li> <li>CV</li> <li>Funding information including any alternative sources of funding that you are applying for or if you are able to pay your own fees and maintenance</li> </ul>
Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.
The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
