Source: Faisal Alamgir, School of Materials Science and Engineering, Georgia Institute of Technology, Atlanta, GA X-ray diffraction (XRD) is a technique used in materials science for determining the atomic and molecular structure of a material. This is done by irradiating a sample of the material with incident X-rays and then measuring the intensities and scattering angles of the X-rays that are scattered by the material. The intensity of the scattered X-rays are plotted as a function of the...

Here, we present a protocol on how to determine the quantity and distribution of metals in a sample using synchrotron X-ray fluorescence. We focus on adherent cells, and describe the chemical fixation method to prepare this sample. We then describe how to mount and image the sample using synchrotron X-rays.

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography. Diffraction Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Source: Laboratory of Dr. Lydia Finney — Argonne National Laboratory X-ray fluorescence is an induced, emitted radiation that can be used to generate spectroscopic information. X-ray fluorescence microscopy is a non-destructive imaging technique that uses the induced fluorescence emission of metals to identify and quantify their spatial distribution.
FAQs
Radiation dose controls whether microbial populations receive enough molecular damage to prevent reproduction. In gamma ray sterilization, the delivered dose must be controlled rather than assumed from exposure time alone, because the goal is to achieve sterility while preserving the product’s performance. Dose selection therefore connects the microbial outcome with material compatibility and is a central part of process validation.
Gamma rays damage microbial DNA and other molecules, disrupting the ability of microorganisms to reproduce. This effect matters because the process must address bacteria, viruses, fungi, and spores rather than a single microbial group. For clinical products, preventing reproduction supports safe use when the delivered dose has been controlled and validation confirms the treatment outcome.
Unlike heat-based processing, Gamma ray sterilization operates at low temperature, and it can reduce the need for chemical treatment. That distinction matters when a product or component must be treated without relying on high heat or chemicals. However, the method is not automatically suitable for every material: compatibility must be assessed alongside the required radiation dose.
Gamma rays can penetrate packaging and dense objects, so treatment can reach the product without opening its protective package. This permits sterilization after packaging and supports clinical use while the product remains packaged. Penetration is particularly important for dense products, including implants, because the radiation can pass through the object rather than being limited to its exterior.
An application begins with the product in its intended package, followed by exposure to a controlled radiation dose. The treated item is then evaluated through validation, with attention to sterility and continued product performance. Material compatibility is considered throughout, so the process addresses microbial elimination without compromising the clinical function of the item.
Examples include single-use syringes, surgical instruments, implants, tissue products, and pharmaceutical components. The breadth of this list reflects the method’s clinical role across packaged devices, implanted materials, tissue-based products, and drug-related components. Selection still depends on whether the material tolerates the controlled dose and whether validation confirms sterility without compromising performance.
Compatibility determines whether the required radiation dose can be applied without compromising product performance. This consideration is important for syringes, instruments, implants, tissue products, and pharmaceutical components because sterilization must support their intended clinical use, not merely produce a microbial outcome. Compatibility assessment therefore accompanies dose control and validation during process planning.
