DNA profiling of trace DNA recovered from bedding
Forensic Science International, 2006Trace DNA is often detected on handled items and worn clothing examined in forensic laboratories. In this study, the potential transfer of trace DNA to bedding by normal contact, when an individual sleeps in a bed, is examined. Volunteers slept one night on a new, lower bed sheet in their own bed and one night in a bed foreign to them. Samples from the

Recovery of trace DNA and its application to DNA profiling of shoe insoles
Forensic Science International, 2004In recent years, the analysis of trace amounts of DNA has become a necessary and useful forensic tool. DNA profiles can be obtained from items that have been worn or handled, due to the presence of transferred DNA derived from skin cells. Shoeprints collected from crime scenes that match a suspects shoe can link a shoe to the crime scene. A DNA profile

Forensic DNA Trace Evidence Interpretation
2023Forensic DNA Trace Evidence Interpretation: Activity Level Propositions and Likelihood Ratios provides all foundational information required for a reader to understand the practice of evaluating forensic biology evidence given activity level propositions and to implement the practice into active casework within a forensic institution.

Voltammetric trace analysis of DNA and RNA
Fresenius' Journal of Analytical Chemistry, 2000A voltammetric determination of DNA/RNA is described. The new aspect is the use of the extracellular endonuclease Serratia marcescens in the sample preparation. Using this enzyme it is possible to determine DNA/ RNA with a detection limit of 2-5 pg/mL. This satisfies the requirements of the WHO and the FDA.

Biochemical Society Transactions, 2001
A number of studies (mainly in vitro and in vivo animal models) have examined the interaction of trace elements with DNA. Normal dietary levels of various trace elements are required to prevent the occurrence of oxidative damage, and deficiency may increase susceptibility. Conversely, overload of some trace elements, including copper and iron, has been

DNA microarray for tracing Salmonella in the feed chain
International Journal of Food Microbiology, 2011In the present study we investigated if the microarray platforms Premi®Test Salmonella (PTS) and Salmonella array (SA) could be applied for the identification and typing of Salmonella in artificially contaminated animal feed materials. The results were compared to the culture-based MSRV method and serotyping according to Kauffman-White. The SA platform

Sensor Review, 2000
A system that began with DNA tagging of oil cargoes has expanded to provide tracers for such diverse commodities as grain, silk, antiques, diamonds, high value documents and packaging. It has been used for a great variety of purposes. One is the covert tracing of marked commodities that have entered the country as “grey” imports, sold at reduced prices.

Capacitive biosensor for quantification of trace amounts of DNA
Biosensors and Bioelectronics, 2009A flow injection capacitive biosensor system to detect trace amounts DNA has been developed based on the affinity binding between immobilized histone and DNA. Histones from calf thymus and shrimp were immobilized on gold electrodes covered with self-assembled monolayer (SAM) of thioctic acid.

Complex kinetics of DNA condensation revealed through DNA twist tracing
Physical Review E, 2015Toroid formation is an important mechanism for DNA condensation in cells. The length change during DNA condensation was investigated in previous single-molecule experiments. However, DNA twist is key to understanding the topological kinetics of DNA condensation.

Extraction and electrochemical detection for quantification of trace-level DNA
Microchimica Acta, 2021A novel strategy was developed to extract, detect, and quantify trace-level DNA. For the extraction step, a composite of methylene blue (MB), poly(acrylic acid) (PAA), and modified iron oxide magnetic nanoparticles (IOMNPs) (PAA/IOMNPs) was used to adsorb DNA from the sample. MB-PAA/IOMNPs with adsorbed DNA were then separated from the solution with an
