Piezo-Based Mechanisms Provide Necessary Precision Required for Laser Eye Surgery

Piezo motion-based mechanisms deliver a range of features preferred in medical engineering and life science applications, such as lubricant-free drives and sterile ceramic designs. The non-magnetic nature of ceramics is an advantageous characteristic in high-energy scanning/imaging based on strong magnetic fields. Precise motion along with incredible speed can be achieved with piezo mechanisms.

Using Miniature Drives for Zoom Control and Focus for Chip-on-the-Tip Endoscopes

The aim of minimal invasive surgery (MIS), as the name suggests, is to cause minimal discomfort to patients. Here, endoscopes play a vital role. However, conventional Chip-on-the-Tip endoscopes that employ fixed focus optics are incapable of displaying objects at various distances with optimum resolution. Variable focusing is achieved by integrating a miniature drive, so that the object is optimally shown in sharp focus all the time.

Key Considerations When Outfitting a Preclinical In Vivo Imaging Laboratory

When setting up a preclinical in vivo imaging laboratory, several factors have to be taken into account which will partly depend on the particular imaging systems in the lab and the expected workflow of research that will be conducted. In addition to these, there are some aspects of laboratory set-up which are essential to meet both regulatory and safety requirements, whilst others are meant to ease routine productivity at the laboratory.

Combining Electron Paramagnetic Resonance and Atomic Force Microscopy to Elucidate Oxidative Stress in Eye Disorders

Oxidative damage is thought to underlie many age-related disorders of the eye, and can be caused by oxidative molecules as well as photooxidation from UV light. The risk of AMD increases with exposure to light, highlighting the detrimental potential of oxidation to the aging eye.

An Overview of Proton Detection in Biological Samples Under Ultra-Fast Magic Angle Spinning

Attributes like natural abundance of over 99.9% and a high gyromagnetic ratio help in the characterization of protons. Thanks to these attributes, a greater detection sensitivity than those of 15N or 13C is obtained which makes 1H-detected NMR spectroscopy extremely attractive, and not only for solution NMR.[1-6]

Using TD-NMR Analysis for Fast and Reliable Quality Control for Toothpaste Production

Many ingredients are added to mouthwash and toothpaste to improve both health benefits and quality. Fluorine is one such ingredient that is added to these items to strengthen tooth enamel and thus prevent cavities. This chemical element is typically added in the amounts of 1000 to 1500 ppm.

Electron Paramagnetic Resonance Aids Cancer Drug Development

Chromosome instability is a key hallmark of cancers, increasing mutation rates and helping tumor cells evade destruction by the immune system as well as treatment by medical interventions. Hypoxia contributes to this instability, causing replication stress and a subsequent loss of the cellular machinery required to deal with DNA damage.

Nuclear Magnetic Resonance Helps Researchers Improve Drug Delivery

Modern medicine has evolved rapidly over the past century, and the development of safe and effective drugs has been a key factor in reducing death and disability from diseases which were once a death sentence. Advances in vaccination led to the complete elimination of small pox by 1990, and as of 2016, polio cases have been reduced by 99% worldwide as well.1,2 Pharmacological agents, such as statins, chemotherapeutics, and anti-retroviral therapies have made incredible progress in treating heart disease, cancer, and HIV/AIDS.

Using Online NMR Reaction Monitoring to Understand Mechanisms and Kinetics of Chemical Reactions

Nuclear magnetic resonance (NMR) is a structurally rich and non-intrusive technique that is quantitative by nature. These inherent characteristics make NMR extremely robust for identifying and characterizing reaction intermediates, thus allowing a better understanding about the kinetics of chemical reactions and reaction mechanisms.
