A method for separating and quantifying organic and inorganic ice nucleating substances in atmospheric samples based on density gradient centrifugation

Ice nucleating substances (INSs) influence the properties and frequencies of ice and mixed-phase clouds in the atmosphere, and hence, climate and the hydrological cycle. INSs can be classified as inorganic (e.g., mineral dust, volcanic ash) or organic (e.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Protocol to isolate quiescent hepatic stellate cells in sufficient yield while maintaining cytokine responsiveness from aged female mice

STAR Protocols
Summary: Isolation of primary hepatic stellate cells (HSCs) in sufficient quantities is technically challenging. We present a protocol for isolating quiescent HSCs from mice using Nycodenz density-gradient centrifugation.

Utilization of a Density Gradient Centrifugation-Based Human PBMC Isolation Assay

, 2022
In the Denton Immunobiology Lab, we research natural killer (NK) cell-mediated combination immunotherapeutic strategies. My primary role in this research is to isolate peripheral blood mononuclear cells (PBMCs) from human blood products.

A Surface‐engineered Microfluidic Device for Antibody‐Mediated Negative Selection of High‐Quality Sperm for Assisted Reproduction

Advanced Functional Materials, EarlyView.
This study reports a microfluidic device with a functionalized surface utilizing a polyoxazoline coating and covalently immobilized gold nanoparticles and anti‐phosphatidylserine antibody. The device efficiently eliminates pre‐apoptotic and apoptotic spermatozoa and yields sperm with substantially improved quality and low DNA damage, offering a simple ...

Density gradient centrifugation of sperm from a subfertile stallion and effect of seminal plasma addition on fertility.

, 2011
Stallions are not selected for fertility but for other criteria (pedigree, conformation, performances, progeny), therefore valuable but subfertile stallions with poor semen quality are frequently used in commercial breeding programs.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
