Book Description
In recent years, thousands of cancer biomarkers have been discovered and described in scientific literature. The promise of personalised medicine, where diseases such as cancer are accurately diagnosed and treatments tailored specifically for individuals, is becoming a reality. Significant advances in biomarker-based research methodologies such as Next Generation Sequencing (NGS) are at the cusp of ushering in a new era of personal medicine. However, unlike the spectacular advances in research technologies for disease biomarker discovery, biomarker-based technologies that can effectively be used in the clinic (or point-of-care) to enable personalised medicine are still lacking. In this book, we feature a selection of emerging technologies which are aimed at enabling clinical applications of personalised medicine. Each of the eight chapters is written by a leading group at the intersection of microfluidics, biology, and nanotechnology. For instance, to accelerate a major bottleneck in the development of clinically useful protein diagnostics, we discuss the application of yeast-derived single chain Fragment variable (scFv) antibody-like molecules as a potential low cost alternative to traditional antibody-based diagnostics. Circulating tumour cells (CTCs) are an emerging class of cancer biomarkers and a potential resource for understanding cancer progression; we explore various strategies combining microfluidics with nanotechnology for capturing CTCs. The book includes an evaluation of some current and emerging technologies for detecting clinical DNA methylation, another potential cancer biomarker. As personalised medicine may involve tracking a patient's response to treatment, the application of microfluidics to detect metabolites in biological fluids is also discussed. Finally, the ultimate goal of personalised medicine is targeted therapy. One promising approach is RNAi technology which uses short nucleotides to disrupt cancer pathways. In this book, nanoparticle approaches to deliver these short nucleotides are discussed.

Book Description
Surface-enhanced Raman spectroscopy (SERS) has immerged as a power analytical and sensing technique for many applications in biomedical diagnosis, life sciences, food safety, and environment monitoring because of its molecular specificity and high sensitivity. The inactive Raman scattering of water molecule makes SERS a suitable tool for studying biological systems. Microfluidic devices have also attracted a tremendous interest for the aforementioned applications. By integrating SERS-active substrates with microfluidic devices, it offers a new capability for in situ investigation of biological systems, their dynamic behaviors, and response to drugs or microenvironment changes. In this work, we designed and fabricated a microfluidic device with SERS-active substrates surrounding by cell traps in microfluidic channels for in situ study of live cells using SERS. The SERS-active substrates are quasi-3D plasmonic nanostructure array (Q3D-PNA) made in h-PDMS/PMDS with physically separated gold film with nanoholes op top and gold nanodisks at the bottom of nanowells. The Q3D-PNAs with the strongest local electric fields (hot spots) at the top and bottom water/Au interfaces, designed by 3D finite-difference time-domain (3D-FDTD) electromagnetic simulations, were placed at the up and down stream of the microfluidic channel for sensitive analysis of cells and small components, respectively. The microfluidic device was fabricated via soft lithography. We demonstrated that normal (COS-7) and cancer (HpeG2) cells were captured on the Q3D-PNAs and investigated in situ using SERS.

Book Description
Combination chemotherapies that introduce multi-agent treatments to target cancer cells are emerging as new paradigms to overcome chemotherapy resistance and side effects involved with conventional monotherapies. In environmental toxicology, characterizing effects of mixtures of toxins rather than simply analyzing the effect of single toxins are of significant interest. In order to determine such combination effects, it is necessary to systematically investigate interactions between different concentration-dependent components of a mixture. Conventional microtiter plate format based assays are efficient and cost-effective, however are not practical as the number of combinations increases drastically. Although robotic pipetting systems can overcome the labor-intensive and time-consuming limitations, they are too costly for general users. Microfluidic live cell screening platforms can allow precise control of cell culture microenvironments by applying accurate doses of biomolecular mixtures with specific mixing ratios generated through integrated on-chip microfluidic gradient generators. This thesis first presents a live cell array platform with integrated microfluidic network-based gradient generator which enables generation and dosing of 64 unique combinations of two cancer drugs at different concentrations to an 8 by 8 cell culture chamber array. We have developed the system into a fully automated microfluidic live cell screening platform with uniform cell seeding capability and pair-wise gradient profile generation. This platform was utilized to investigate the gene expression regulation of colorectal cancer cells in response to combination cancer drug treatment. The resulting cell responses indicate that the two cancer drugs show additive effect when sequential drug treatment scheme is applied, demonstrating the utility of the microfluidic live cell assay platform. However, large reagent consumption and difficulties of repeatedly generating the exact same concentrations and mixture profiles from batch to batch and device to device due to the fact that the generated gradient profiles or mixing ratios of chemicals have to rely on stable flow at optimized flow rate throughout the entire multi-day experiment limit the widespread use of this method. Moreover, producing three or more reagent mixtures require complicated microchannel structures and operating procedures when using traditional microfluidic network-based gradient generators. Therefore, an on-demand geometric metering-based mixture generator which facilitates robust, scalable, and accurate multi-reagent mixing in a high-throughput fashion has been developed and incorporated with a live cell array as a microfluidic screening platform for conducting combination drug or toxin assays. Integrated single cell trapping array allowed single cell resolution analysis of drugs and toxin effects. Reagent mixture generation and precise application of the mixtures to arrays of cell culture chambers repeatedly over time were successfully demonstrated, showing significantly improved repeatability and accuracy than those from conventional microfluidic network-based gradient generators. The influence of this improved repeatability and accuracy in generating concentration specified mixtures on obtaining more reliable and repeatable biological data sets were studied.

Book Description
Raman spectroscopic measurements of cell death due to combined oxy-glucose deprivation showed that dead cells had relatively higher amounts of protein and DNA and lower amounts of lipid and RNA compared to live cells. Changes due to protein, lipid and nucleic acids were observed in the spectra of dead cells. To the best of our knowledge, this is the first Raman study of cell-death in monolayer cultures due to combined oxy-glucose deprivation.
