Thermal Properties of Lipid Bilayers Determined Using Upconversion Nanothermometry

Advanced Functional Materials, 2019
Luminescent nanomaterials have shown promise for thermal sensing in bio‐applications, yet little is known of the role of organic coatings such as supported lipid bilayers on the thermal conductivity between the nanomaterial and its environment ...

CryoEM reveals how the complement membrane attack complex ruptures lipid bilayers

Nature Communications, 2018
The membrane attack complex (MAC) is one of the immune system’s first responders. Complement proteins assemble on target membranes to form pores that lyse pathogens and impact tissue homeostasis of self-cells.

Water permeation through stratum corneum lipid bilayers from atomistic simulations [PDF]

, 2009
Stratum corneum, the outermost layer of skin, consists of keratin filled rigid non-viable corneocyte cells surrounded by multilayers of lipids. The lipid layer is responsible for the barrier properties of the skin.

Cholesterol's location in lipid bilayers [PDF]

Chemistry and Physics of Lipids, 2016
It is well known that cholesterol modifies the physical properties of lipid bilayers. For example, the much studied liquid-ordered Lo phase contains rapidly diffusing lipids with their acyl chains in the all trans configuration, similar to gel phase bilayers. Moreover, the Lo phase is commonly associated with cholesterol-enriched lipid rafts, which are

Mesoporous Silica Nanoparticle-Supported Lipid Bilayers (Protocells) for Active Targeting and Delivery to Individual Leukemia Cells.

ACS Nano, 2016
Many nanocarrier cancer therapeutics currently under development, as well as those used in the clinical setting, rely upon the enhanced permeability and retention (EPR) effect to passively accumulate in the tumor microenvironment and kill cancer cells ...

Evidence for the Formation of Symmetric and Asymmetric DLPC-DAPC Lipid Bilayer Domains

Cellular Physiology and Biochemistry, 2013
Background/Aims: We investigated if mixtures of the phosphatidylcholine (PC) lipids 1,2-dilauroyl-sn-glycero-3-phosphocholine (C12:0 PC; DLPC) and 1,2-diarachidoyl-sn-glycero-3-phosphocholine (C20:0 PC; DAPC), which differ by eight methylene groups in ...
