Density-Gradient-Free Microfluidic Centrifugation for Analytical and Preparative Separation of Nanoparticles

, 2016
Sedimentation and centrifugation techniques are widely applied for the separation of biomolecules and colloids but require the presence of controlled density gradients for stable operation. Here we present an approach for separating nanoparticles in free

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,

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.

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

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.

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.

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance
