Book Description
This thesis includes the synthesis, conjugation and applications of nano and microparticles for the detection and diagnosis of clinically important units such as cell lysates or proteins. Chapter one presents details of the synthesis and characterization of aptamer-AuNP conjugates for the detection of proteins based on dynamic light scattering. Additions of proteins to aptamer-conjugated gold nanoparticles (AuNPs) induced the formation of dimers, trimers, oligomers or aggregates. The average hydrodynamic diameter of the aggregates as measured by DLS, increased with the corresponding increase in protein concentration. This correlation formed the analytical basis of the assay. A linear dynamic range of up to 300 nM (1800 nm) and Limit of detection of 2.67nM was realized using thrombin as the model analyte. This thesis also discusses a novel surface-based method to detect cancer cell membrane using lateral flow technology. This is conceptualized based on familiar streptavidin-biotin and lectin-glycan interactions. Here the detection of cancer cells membranes is based on a differential expression of sialic acids on cancerous cells as compared to the normal cells. The lateral flow biosensor constructed was able to corroborate successful detection cancer cell membranes in less than 40 minutes, qualitatively.

Book Description
Nano- and Microfabrication for Industrial and Biomedical Applications, Second Edition, focuses on the industrial perspective on micro- and nanofabrication methods, including large-scale manufacturing, the transfer of concepts from lab to factory, process tolerance, yield, robustness, and cost. The book gives a history of miniaturization and micro- and nanofabrication, and surveys industrial fields of application, illustrating fabrication processes of relevant micro and nano devices. In this second edition, a new focus area is nanoengineering as an important driver for the rise of novel applications by integrating bio-nanofabrication into microsystems. In addition, new material covers lithographic mould fabrication for soft-lithography, nanolithography techniques, corner lithography, advances in nanosensing, and the developing field of advanced functional materials. Luttge also explores the view that micro- and nanofabrication will be the key driver for a "tech-revolution" in biology and medical research that includes a new case study that covers the developing organ-on-chip concept. Presents an interdisciplinary approach that makes micro/nanofabrication accessible equally to engineers and those with a life science background, both in academic settings and commercial R&D Provides readers with guidelines for assessing the commercial potential of any new technology based on micro/nanofabrication, thus reducing the investment risk Updated edition presents nanoengineering as an important driver for the rise of novel applications by integrating bio-nanofabrication into microsystems

Book Description
This contributed volume applies the insights of supramolecular chemistry to biomedical applications such as ions/water transport through nano-scale channels, gene therapy, tissue engineering and drug delivery, to cite some of the major investigations.The challenge is to understand the mechanisms of transport through tissues particularly in the therapeutic treatment of a disease where the active drug must be delivered directly to diseased cells without affecting healthy cells. As a result, smaller quantities of active substances can be used to treat the disease. Another interest concerns new ways to administer gene therapy. If genes are often delivered to their target cells by adapted viruses, the supramolecular non-viral ‘vectors’ using dynamic nano-frameworks and nano-structures are presented. In addition, it is important to reconstruct damaged tissues by mimicking natural processes in cells and polymers, such as tissue engineering and self-healing. Different options are here discussed: e.g. hydrogels based on chitosan, a carbohydrate polymer, are proving especially promising for tissue engineering and drug delivery. For controlled delivery of drugs or other biologically active compounds, hydrogels sensitive to the most important stimuli in the human body, such as temperature, pH, ionic strength, glucose and biomolecules released by the organism in pathological conditions have been developed. Finally, to assist and validate the experimental studies, computer modelling and simulations of large-sized molecular structures and systems using different molecular dynamics and quantum mechanical techniques are developed based on the experimental and chemistry synthesis. This book is of great interest for graduate students, researchers and health professionals interested in acquiring a better understanding of the mechanisms of medical treatments. In addition, it provides numerous tools to develop better therapies for human diseases.
