abstract = {High-performing sensors have played a pivotal role in expanding our understanding of biological systems, disease diagnosis, environmental monitoring, and national security. The technical capability they provide has enabled us to obtain in-depth information and insights towards improving human health. One area of sensing that exemplifies this progress is the development of label free sensors which allow direct analysis of molecular interactions. Among these methods surface plasmon resonance (SPR) has emerged as a powerful, real-time detection technique for studies of biological interactions, drug discovery, and other important aspects that lead to new disease diagnosis. Through the implementation of new materials and methods SPR and other label-free sensors have expanded the range of analytes tested. This Dissertation aims to establish improvements in materials and methodologies through technology advancement for solving current sensor limitations. The work focuses on enhancing sensing signal while limiting the impact of nonspecific interactions on label-free methods, providing expanded molecular identity information, and overcoming challenges encountered when detecting small molecules. Chapters 2, 3, and 4 demonstrate advancements in unique biomimetic surfaces to enable the exploration of new biological systems as well as block nonspecific interactions. Chapter 2 focuses on a tethered membrane system to promote incorporation of relevant constituents into lipid bilayers without compromising membrane mobility property and drug delivery interactions. Chapter 3 employs a charged membrane to suppress nonspecific interactions and explores the working mechanism. Chapter 4 expands the capabilities of label-free sensing systems through development of curved membrane platforms that mitigate the decay limits through modeling of lipid distribution in vesicles. Chapter 5 exploits the plasmonic properties of SPR chips to enhance signals in matrix assisted laser desorption ionization mass spectrometry (MALDI-MS) , which is further facilitated with development of machine learning models to identify bacterial species. In Chapter 6, the limitation of small molecule analysis with SPR is tackled by taking advantage of pressure effects to provide specific gas sensing. Each of these Chapters provides novel advancements in sensing capabilities by addressing performance-impairing limitations in label-free sensors. Research goals are achieved both from improvements to SPR systems and incorporation of other methodologies to augment SPR results.},

abstract = {In the present work, we developed an effective antimicrobial surface film based on sustainable microfibrillated cellulose. The resulting porous cellulose thin film is barely noticeable to human eyes due to its submicrometer thickness, of which the surface coverage, porosity, and microstructure can be modulated by the formulations and the coating process. Using goniometers and a quartz crystal microbalance, we observed a threefold reduction in water contact angles and accelerated water evaporation kinetics on the cellulose film (more than 50% faster than that on a flat glass surface). The porous cellulose film exhibits a rapid inactivation effect against SARS-CoV-2 in 5 min, following deposition of virus-loaded droplets, and an exceptional ability to reduce contact transfer of liquid, e.g., respiratory droplets, to surfaces such as an artificial skin by 90% less than that from a planar glass substrate. It also shows excellent antimicrobial performance in inhibiting the growth of both Gram-negative and Gram-positive bacteria (Escherichia coli and Staphylococcus epidermidis) due to the intrinsic porosity and hydrophilicity. Additionally, the cellulose film shows nearly 100% resistance to scraping in dry conditions due to its strong affinity to the supporting substrate but with good removability once wetted with water, suggesting its practical suitability for daily use. Importantly, the coating can be formed on solid substrates readily by spraying, which requires solely a simple formulation of a plant-based cellulose material with no chemical additives, rendering it a scalable, affordable, and green solution as antimicrobial surface coating. Implementing such cellulose films could thus play a significant role in controlling future pan- and epidemics, particularly during the initial phase when suitable medical intervention needs to be developed and deployed.},

abstract = {The need for rapidly developed diagnostic tests has gained significant attention after the recent pandemic. Production of neutralizing antibodies for vaccine development or antibodies to be used in diagnostic tests usually require the usage of recombinant proteins representing the infectious agent. However, peptides that can mimic these recombinant proteins may be rapidly utilized, especially in emergencies such as the recent outbreak. Here, we report two peptides that mimic the receptor binding domain of the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and investigate their binding behavior against the corresponding human immunoglobulin G and immunoglobulin M (IgG and IgM) antibodies in a clinical sample using a quartz crystal microbalance (QCM) sensor. These peptides were immobilized on a QCM sensor surface, and their binding behavior was studied against a clinical serum sample that was previously determined to be IgG and IgM-positive. It was determined that designed peptides bind to SARS-CoV-2 antibodies in a clinical sample. These peptides might be useful for the detection of SARS-CoV-2 antibodies using different methods such as enzyme-linked immunosorbent assay (ELISA) or lateral flow assays. A similar platform might prove to be useful for the detection and development of antibodies in other infections.},
