New nanotransporter for drug delivery inside cells

A new study by the University of Barcelona has analyzed the viability of a new nanomolecule as drug delivery vehicle. The results, published in the journal Colloids and Surfaces B: Biointerfaces, show that liposomes designed ...

When was the first time life began to prey on each other?

Using the word predation may seem surprising when we talk about the first organisms that set out to eat other organisms, for they were not deadly predators with sharp teeth and claws, but small single-celled life forms that ...

Cell membrane

The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.

It is a semipermeable lipid bilayer found in all cells. It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance and cell signaling. The plasma membrane also serves as the attachment point for both the intracellular cytoskeleton and, if present, the extracellular cell wall.
