Research news on Biological materials

Biological materials, as physical systems, comprise substances produced by or derived from living organisms, characterized by hierarchical organization from molecular to macroscopic scales and emergent structure–property relationships. They include tissues, extracellular matrices, biominerals, and biopolymers such as collagen, chitin, cellulose, and elastin. Their properties arise from complex architectures combining organic and often inorganic phases, enabling functions such as load bearing, protection, adhesion, and signal transduction. Biological materials exhibit viscoelasticity, anisotropy, self-healing, and adaptive remodeling under mechanical or biochemical stimuli, making them central model systems for biomechanics, biomimetics, and the design of advanced bioinspired and biomedical materials.

DNA provides a solution to our enormous data storage problem

Since the dawn of the computer age, researchers have wrestled with two persistent challenges: how to store ever-increasing reams of data and how to protect that information from unintended access. Now, researchers with Arizona ...

Novel nanomaterial uses oxidative stress to kill cancer cells

Scientists at Oregon State University have developed a new nanomaterial that triggers a pair of chemical reactions inside cancer cells, killing the cells via oxidative stress while leaving healthy tissues alone. The study ...

New nanoparticle technology offers hope for hard-to-treat diseases

A newly published Perspective article in Nature Nanotechnology details groundbreaking nanoparticle technology to eliminate harmful, disease-causing proteins in the body. The technology marks a transformative leap in the potential ...

Hydrogel cilia set new standard in microrobotics

Cilia are micrometer-sized biological structures that occur frequently in nature. Their characteristic high-frequency, three-dimensional beating motions (5–40 Hz) play indispensable roles inside the body.

Coffee as a staining agent substitute in electron microscopy

To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is uranyl acetate. However, some ...
