Bioanalytical
Rapid Bioanalytical Methods
Research Goals
The primary goal of our bioanalytical research is concerned with developing rapid, quantitative spectroscopic based techniques for the non-contact, non-destructive analysis of the complex materials (e.g. raw materials, cell culture media, bioprocess broths) encountered in biological based pharmaceutical manufacturing.
The value of the methods that we are developing lies in the fact that they are inexpensive and suitable for screening all the materials used in a BioPharmaceutical manufacturing process.
These methods are designed to be very rapid, require no expensive training or consumables and are also perfectly suited to use in aseptic methods of production and harsh environments.
To date (Nov. 2024) we have mostly focused on the quantitative analysis of cell culture media, the raw materials used for medias, and bioprocess broths. In 2024 a new project started which is looking at downstream processing of monoclonal antibodies and large biological systems.
Current Projects
We are currently undertaking a wide variety of individual research projects. In general, the work involves the use of spectroscopic techniques like Atomic Emission Spectroscopy, Raman, FT-IR, FT-NIR, SERS, UV-VIS, DLS, and multi-dimensional Fluorescence for the quantitative analysis of complex mixtures. The spectroscopic data is then analyzed using advanced chemometric methods which are developed in-house. In the final stages of the research we also engage in the technical transfer activities required e.g. preparation of Standard Operating Procedures, Validation experiments, etc. Details will be posted as and when they are accepted for publication, however much of what we do is covered by confidentiality agreements.
Downstream Protein Analysis - Polarized Emission Spectroscopy (DPA-PES), 2024-29:
This project will invoved a team of 2 x Postdocs, and 4 x PhD students working on various aspects of the research programme. Recruitment is ongoing and more details will be uploaded from time to time.
MNC 2 (2024-26):
This project is developing novel analytical methods for large macromolecules. This research involves the use of Fluorescence spectroscopy.
Horiba (2021-present):
We are collaborating with Horiba on the use of fluorescence EEM measurements for biopharmaceutical manufacturing applications using their Aqualog CCD based fluorescence spectrometer. We currently have two Aqualogs installed in the lab, configured for pEEM measurements in cuvettes and in flow.
Completed Projects:
CBAS (Phase 1, BMS), 2005-09:
A team of ~10 researchers was based in the Nanoscale Biophotonics Laboratory on this project. The CBAS project was a collaboration with Bristol-Myers Squibb and Dublin City University and is funded by the IDA and BMS.
Press releases on the project can be found on the Galway Advertiser, and IDA website.
A discussion piece is also available on: Pharma Manufacturing.Com.
This project is now complete and we published multiple outcomes from this research.

Subsequent follow-on projects expanded on these initial studies and we were engaged in a variety of studies using Raman and Fluorescence spectroscopies. There were two postdoctoral researchers engaged full-time on this project.

Selected Results
We will upload data when appropriate. We expect to be able to publish a range of manuscripts detailing our work over the past 5 years, once reviewed by our industrial partners. In the meantime the published manuscripts should provide an overview of what has been done to date.
Cell culture media:
Mammalian cell culture is increasingly being used for the manufacture of recombinant protein based therapeutics. One of the key components of the cell culture manufacturing process is the area of cell culture media (CCM). The fields of CCM formulation, storage, feeding, and analysis is a critical area of bio-analytical science which is complicated by the fact the CCMs are very complex and sensitive materials, particularly when in liquid form. CCMs can consist of a wide variety of diverse components: sugars, amino acids, proteins, vitamins, inorganic salts and other nutrients. However the rapid, online, non-destructive, and quantitative analysis of CCMs is currently and under-developed area, but there is an urgent need for these types of methods. Rapid and/or real-time monitoring of CCM composition would provide a tool to improve process control and product yield. To optimize the product yield, the CCM composition and feeding rates must be tightly controlled.
Motivated by the need for rapid, non-contact, non-destructive and inexpensive methods of analysis for these complex CCM mixtures, we are exploring the application of Raman and Fluorescence spectroscopy coupled with mathematical analysis for robust, reliable, and rapid CCM characterization.
Jan. 11: Our work on rapid cell culture media analysis was featured in the January issue of Genetic Engineering & Biotechnology News. The article can be accessed here.
Bioprocess broths:
The analysis of complex cell culture process broths is challenging, time-consuming, and expensive due to the fact that they are complex mixtures and consist of a vast variety of components, e.g., inorganic salts, sugars, amino acids, proteins, vitamins, and other nutrients. This thus requires the development of holistic and inexpensive methods that can elucidate compositional information from these complex mixtures for diagnostic and process control purposes. Here we have used a range of spectroscopic methods coupled with advanced Chemometrics to develop a suite of characterization tools which are all suited to online process control. We have published two main studies in collaboration with Bristol-Myers Squibb on the use of fluorescence EEM and Raman spectroscopy respectively. In both studies it was possible to use the spectral data to predict process performance (in terms of final product yield) at an early stage in the bioprocess.
BioPharma raw materials:
A lot of the raw materials or third party supplied media components are very complex mixtures (solid or liquid) and they are challenging from an ID and quality assessment point of view. We have developed a range of very inexpensive ID and quality tools for use in both the QC lab and in the storeroom.
