Micromachined needles for microbiological sample and drug delivery system

Proceedings International Conference on MEMS, NANO and Smart Systems, 2004
In this paper, the research and development of micromachined needles for microbiological sample and drug delivery system are reviewed. The micromachined needles can be classified into in-plane and out-of-plane needles. The features of those microneedles are analyzed and discussed.

Sample Delivery Techniques for Serial Crystallography

2018
In serial femtosecond crystallography (SFX), protein microcrystals and nanocrystals are introduced into the focus of an X-ray free electron laser (FEL) beam ideally one-by-one in a serial fashion. The high photon density in each pulse is the double-edged sword that necessitates the serial nature of the experiments.

Sample delivery for structural biology at the European XFEL

Serial femtosecond crystallography (SFX) at X-ray free electron lasers (XFELs) is a valuable technique for time-resolved structural studies on enzymes. This method allows for the collection of high-resolution datasets of protein structures at various time points during a reaction initiated by light or mixing.

Umbilical cord blood sampling — a tool for delivery quality control?

Acta Obstetricia et Gynecologica Scandinavica, 1997
Background. Regular cord blood analysis post partum is regarded by many as one of the most accurate and objective methods of auditing intrapartum care. Emergency cesarean sections and ventouse deliveries, due to the threat of asphyxia, are examples where post partum acid base data from the umbilical artery ought to be a must.

Predicting Water Quality for the Woronora Delivery Network with Sparse Samples

2019 IEEE International Conference on Data Mining (ICDM), 2019
Monitoring drinking water quality in the entire delivery network, mainly indicated by total chlorine (TC), is a critical component of overall water supply management. However, it is extremely difficult to collect sufficient TC data from the network at customer sites, which makes it sparse for comprehensive modelling. This paper details an approach that

Iron deficiency is prevalent in a sample of pregnant women at delivery in Germany

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2002
To determine the prevalence and risk factors of iron deficiency in pregnancy, since iron supplements are not routine in Germany.Soluble transferrin receptor (sTfR), ferritin, hemoglobin (Hb), C-reactive protein (CRP) and leucocyte counts were determined in venous blood samples of 378 women before delivery; 191 of them filled in a questionnaire ...

Sample Preparation and Delivery

As a direct-analysis technique, SIFT-MS has differing sample preparation and sample delivery requirements to GC, the most widely used technique for analysing volatile compounds. This chapter summarises the general principles of effective sample delivery to SIFT-MS instruments, with reference to the GC methods.

Optical techniques and microtools for subcellular delivery and sampling

2017
The vast majority of biochemical and histological assays are conducted upon ensembles of tens or hundreds or thousands of cells. However, there is a robust and increasing volume of evidence that small subpopulations of cells play significant roles in the development of many disease states, and particularly in their evolution toward treatment resistance.
