Mussel‐Inspired Molecular Strategies for Fabricating Functional Materials With Underwater Adhesion and Self‐Healing Properties

Advanced Materials, EarlyView.
This review systematically examines the nanomechanical mechanisms of mussel‐inspired molecular interactions, primarily investigated by direct force measurement techniques such as surface forces apparatus and atomic force microscopy. The macroscopic adhesive and self‐healing performances of mussel‐inspired functional materials, including coacervates ...

Immunological Characterization of the Subunit of the 100 angstrom Filaments from Muscle Cells [PDF]

, 1976
We report the immunological characterization of the subunit of the intermediate sized (100 angstrom) filaments from muscle cells. The protein as isolated from smooth muscle (chicken gizzard) has an apparent molecular weight of 50,000.

Characterization of Knots and Links Arising From Site-specific Recombination on Twist Knots

, 2011
We develop a model characterizing all possible knots and links arising from recombination starting with a twist knot substrate, extending previous work of Buck and Flapan. We show that all knot or link products fall into three well-understood families of

Natural Design of a Stabilized Cross‐β Fold: Structure of the FuA FapC from Pseudomonas Sp. UK4 Reveals a Critical Role for Stacking of Imperfect Repeats

Advanced Materials, EarlyView.
We report a 3.2 Å cryoEM structure of functional amyloid protein FapC from Pseudomonas sp. UK4, an essential component of bacterial biofilm, which reveals a Greek key‐shaped protofilament, supports bioinformatically determined motifs, nuances AlphaFold predictions, emphasizes heterogeneous cross‐β stacking in amyloid cross‐seeding and shows strain ...

Red Blood Cell Membrane‐Camouflaged Red Phosphorus‐Modified C3N4 for Enhanced Tumoral Photodynamic Therapy

Advanced Materials Interfaces, EarlyView.
Photodynamic therapy (PDT) faces clinical challenges due to poor tumor targeting and systemic toxicity. Herein, a biomimetic C3N4‐RP@RBCm nanoplatform is developed via erythrocyte membrane encapsulation, enabling CD47‐mediated immune evasion and EPR‐driven tumor accumulation.

Isolation and properties of lipoproteins from normal rat serum

Journal of Lipid Research, 1969
Three major classes of lipoproteins (VLDL, d < 1.006; LDL, d 1.006-1.040; HDL, d 1.063-1.21) were isolated by ultracentrifugal flotation from the serum of normal male Sprague-Dawley rats.

Increased Small Dense LDL and Decreased Paraoxonase Enzyme Activity Reveals Formation of an Atherogenic Risk in Streptozotocin-Induced Diabetic Guinea Pigs

Journal of Diabetes Research, 2013
This study aimed to investigate LDL subfraction distribution as well as serum cholesteryl ester transfer protein (CETP), lecithin-cholesterol acyltransferase (LCAT), and paraoxonase (PON1) activity in streptozotocin-induced diabetic guinea pigs ...

Biocompatibility and Long‐Term Stability of DNA‐Based Organic Mixed Conductors for Bioelectronics

Advanced Materials Interfaces, EarlyView.
The biocompatibility and long‐term stability of DNA‐based mixed ionic‐electronic conductors are investigated. In vitro cytotoxicity and cell viability are assessed using flow cytometry assay on primary mouse fibroblasts cultures. The biocomposites are integrated into organic electrochemical transistors (OECTs) to determine the stability of their ...

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.
