Separation of Bacteria, Protozoa and Carbon Nanotubes by Density Gradient Centrifugation [PDF]

open access: yesNanomaterials, 2016
Sustainable production and use of carbon nanotube (CNT)-enabled materials require efficient assessment of CNT environmental hazards, including the potential for CNT bioaccumulation and biomagnification in environmental receptors.

Microfluidic Adaptation of Density-Gradient Centrifugation for Isolation of Particles and Cells [PDF]

open access: yesBioengineering, 2017
Density-gradient centrifugation is a label-free approach that has been extensively used for cell separations. Though elegant, this process is time-consuming (>30 min), subjects cells to high levels of stress (>350 g) and relies on user skill to ...

Fractionating microplastics by density gradient centrifugation: a novel approach using LuerLock syringes in a low-cost density gradient maker

open access: yesChemistry Teacher International
Microplastics are now ubiquitous in the environment and are even considered “technofossils” of the Anthropocene. Given their omnipresence and potential impact, identifying and analyzing these particles becomes increasingly crucial.

Single-cell mass-density measurements using microchannel gradient centrifugation

open access: yesScientific Reports
We present a microchannel-based adaptation of mass density-gradient centrifugation for the mass density measurement of cells or microparticles. The workflow consists of three basic steps: Microchannel filling, centrifugation, and microscopy. Microchannel

New device for sperm preparation involving migration-gravity sedimentation without centrifugation compared with density-gradient centrifugation for normozoospermic intrauterine insemination [PDF]

open access: yesF&S Reports, 2020
Objective: To investigate the efficacy of a new device for sperm preparation involving migration-gravity sedimentation without centrifugation (MIGLIS), compared with density-gradient centrifugation (DGC) for normozoospermic intrauterine insemination (IUI)

Sperm sexing with density gradient centrifugation in dogs

open access: yesAnimal Reproduction Science, 2018
Sexed sperm in dogs is of interest because of being polytocous, and as a result, the greatest number of offspring of the same sex can improve the market, although few studies assessing sperm sexing have been performed in this species. The present study, therefore, was conducted to evaluate the effects on sperm quality and the effectiveness of three ...

Helper-free Production of Laboratory Grade AAV and Purification by Iodixanol Density Gradient Centrifugation [PDF]

open access: yesMolecular Therapy: Methods & Clinical Development, 2018
Adeno-associated virus (AAV) is one of the most promising gene therapy vectors and is widely used as a gene delivery vehicle for basic research. As AAV continues to become the vector of choice, it is increasingly important for new researchers to have ...
