Coronavirus information for applicants and offer holders

We hope that by the time you’re ready to start your studies with us the situation with COVID-19 will have eased. However, please be aware, we will continue to review our courses and other elements of the student experience in response to COVID-19 and we may need to adapt our provision to ensure students remain safe.

<h2 class="heading hide-accessible">Summary</h2>

The goal of this project is the creation of a novel microfluidic platform that will be applied to develop a high resolution microscope. Microfluidics is the science and technology of systems that control a small amount (nano- to atto- liters) of liquids in channels with dimensions of between 10 and 100m. It is emerging as an essential component of the new generation of nanoscale (super-resolution) microscopy methods which have transformed Cell and Molecular Biology over the last decade. Some of the latest super-resolution techniques include DNA-PAINT and Expansion Microscopy (ExM) which promise spatial resolution of mere nanometres for visualising proteins and molecules within biological samples. One limitation in the current state of the art is its inability to standardise the intrinsic chemistry of the samples and the excessive manual handling of the biological structures. Microfluidic devices promise a unique opportunity to control the precise chemistry and the dimensions of the sample and enable researchers to carry out the super-resolution imaging in non-specialised instruments.<br /> <br /> In this project, we will develop a new microfluidic device which can perform ExM (a concept that we call MicroExM) on different cell types (supplied by Dr Jayasinghe&rsquo;s group). The MicroExM device will then be trialled on various imaging platforms including commercially available fluorescence microscopes and custom-built super-resolution microscopy systems. Built-into the MicroExM device, will be a DNA-based calibration system which reports the internal chemical environment of the sample and the spatial resolution that is achieved in the optical images.<br /> <br /> A principal outcome of the project will be a versatile and novel platform which makes ExM a robust and versatile super-resolution microscopy technique that is available to a wider community of Cell and Molecular Biologists than at present.<br /> <br /> <br />

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="">University&#39;s website</a>. Please state clearly in the Planned Course of Study that you are applying for <em><strong>PHD Physics &amp; Astronomy FT</strong></em> and&nbsp;in the research information section&nbsp;that the research degree you wish to be considered for is <span style="font-family:&quot;Calibri&quot;,sans-serif; font-size:13pt; line-height:115%; mso-ansi-language:EN-GB; mso-ascii-theme-font:minor-latin; mso-bidi-font-family:Arial; mso-bidi-language:AR-SA; mso-fareast-font-family:&quot;Malgun Gothic&quot;; mso-fareast-language:KO; mso-fareast-theme-font:minor-fareast; mso-hansi-theme-font:minor-latin"><font color="#000000"><em><strong>Development of a high resolution microscope using microfluidic technology</strong></em> </font></span>as well as&nbsp;<a href="">Dr Jung-uk Shim</a> as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p>&nbsp;</p>

<h2 class="heading heading--sm">Entry requirements</h2>

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.

<h2 class="heading heading--sm">English language requirements</h2>

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.
