One of Smith’s most innovative studies, published in the journal ACS Central Science in 2023 (1), introduced a modernized ML approach to illuminate enzyme immobilization for biocatalysis. This innovative work, featured on the journal’s front cover, combined Raman spectroscopy and hyperspectral imaging with non-negative matrix factorization-based ML. This research provided a method to allow for the spatial resolution and molecular identification of immobilized enzyme systems, significantly advancing pharmaceutical biocatalysis and protein engineering efforts (1).
In 2022, Smith’s work on in situ real-time monitoring of emulsification and homogenization processes for vaccine adjuvants was published in Analyst, and this research marked a pivotal advancement in PAT-based analytical methods. By integrating Raman spectroscopy, focused beam reflectance measurements (FBRM), and inline optical microscopy, this work provided real-time analysis of vaccine adjuvant production, resulting in an innovative approach to enhance the efficiency and reliability of vaccine production (2).
Another significant contribution by Smith is his 2022 study on process monitoring of polysaccharide deketalization for vaccine bioconjugation development, published in the Journal of Pharmaceutical and Biomedical Analysis. In this work, Smith developed an FT-IR spectroscopy-based in situ PAT tool for pneumococcal conjugate vaccine production, enabling real-time monitoring of the polysaccharide deketalization processes, thus facilitating scalable and efficient vaccine development (3).
Smith’s publication in Spectrochimica Acta Part A introduced an in-line PAT method using Raman spectroscopy for real-time analysis of cysteine during pharmaceutical processes (4). This method allows for monitoring dynamic concentration changes, providing a unique tool applicable across small molecules, biologics, and vaccines.
In 2021, Smith published work in the journal Analytical Chemistry employing Raman spectroscopy and hyperspectral imaging (HSI) with multivariate curve resolution (MCR) to elucidate enzyme immobilization for biocatalysis (5). This method quantifies enzyme coverage on immobilized supports, offering a rapid and definitive evaluation of immobilized enzyme processes, thereby benefiting pharmaceutical research and development.
Smith’s contributions to research extend beyond his most notable works.
