Abstract:
In den letzten Jahren gab es rasche Weiterentwicklungen auf dem Gebiet der Nukleinsäure-Erkennung. Von microRNA-Quantifizierung zur Untersuchung von Zelltods, --Teilung und -Regulation bis zur Bewertung genetischer Variabilität in Hinblick auf Krankheitsentstehung und -Behandlung: Die Analyse von Nukleinsäuren wird in der zukünftigen Medizin eine zentrale Rolle zukommen. Vor allem die Erkennung von SNPs als Hauptquelle der genetischen Vielfalt, aber aus Analysesicht auch eine der herausforderndsten Mutationen, stellt in dieser Hinsicht einen wesentlichen Aspekt dar.

Abstract:
PCR is commonly used for detecting contamination of foods by toxigenic bacteria. However, it is unknown whether it is suitable for detecting toxins in samples which are unlikely to contain bacterial cells, such as purified biological weapons. Quantitative real-time PCR assays were developed for amplification of the genes encoding Clostridium botulinum neurotoxins A to F, Staphylococcal enteroxin B (SEB), ricin, and C. perfringens alpha toxin. Botulinum neurotoxins, alpha toxin, ricin and V antigen from Yersinia pestis were purified at Dstl using methods including precipitation, ion exchange, F

Abstract:
There has been much interest in recent years about the potential of microRNA as a new source of biomarkers for the diagnosis of disease. The delivery of new diagnostic tools based on this potential has been limited by shortcomings in current microRNA detection techniques. This thesis explores the development of a new method of microRNA detection through the incorporation of conductive particles into oligonucleotide-functionalised polymers to form oligonucleotide cross-linked polymer composites. Such composites could provide a simple, rapid, and low-cost means of microRNA detection that could b

Abstract:
Nucleic acids are key macromolecules of living organisms transferring genetic inheritance from one generation to the next. From how a living individual is created to how it interacts with external factors, all and all, can be found in the nucleic acid sequences inside every single cell of every organism. Therefore, the analysis of nucleic acids sequences is a critical capability for cancer and pathogen diagnoses, genotyping, and disease monitoring. To date, numerous methods have been used to detect both characterised and uncharacterised mutations and sequence variations. However, the detection

Abstract:
In this project, a gold nanoparticle system has been developed that is able to detect SNP variations through a DNA based anthracene probe. A second probe is bound to the gold nanoparticle which allows the fluorescent output of the anthracene probe to be normalized. This allows the detection of SNP variations without the need for an initial reading, opening the possibility for using this system for cellular SNP identification. Through this work a new method for coating gold nanoparticles in oligonucleotides has been developed. In further work, the use of gold nanoparticles to deliver siRNA into

Abstract:
This thesis presents biophysical studies of new optoelecronically active DNA-binders. Chapter one gives a brief overview of the importance of DNA in medicine, of DNA structure and of the mode of interactions of small molecules with double-stranded DNA, including electrostatic, intercalation and groove interactions. Various examples of small-molecule binding to DNA are discussed. Additionally, this chapter briefly describes the biophysical techniques which can be exploited to quantify the interaction between small-molecules and duplex DNA. Chapter two describes the results of studies of the int

Abstract:
Nucleic acid detection is of central importance for the diagnosis and treatment of genetic diseases, infectious agents, bio-warfare agents, and drug discovery. Nucleic acid testing for diseases is exclusively performed in laboratories using high-end instrumentation and personnel. However, this has developed the need for point of care diagnostics which can provide near-patient testing in a clinic, doctor’s office, or home. Such diagnostic tools can prove advantageous when rapid response is required or when suitable facilities are unavailable. Compared to equivalent methods used in laboratories,
