Smart nanocarrier: self-assembly of bacteria-like vesicles with photoswitchable cilia.

چکیده
Bioinspired cell deformation aids in the design of smart functional molecular self-assemblies. We report on a system of bacteria-like vesicles which release entrapped drug upon developing hairs triggered by UV irradiation, just like cilia stretching from the surface of bacteria. The formation of cilia leads to a less intact membrane, which allows release of entrapped drug. This bioinspired design created a smart nanocarrier that releases the payload via deformation rather than complete breaking.

متن کاملDiamondoids and DNA Nanotechnologies
Diamondoids are cage-like saturated hydrocarbons consisting of fused cyclohexane rings. The Diamondoids family of compounds is one of the best candidates for molecular building blocks (MBBs) in nanotechnology to construct organic nanostructures compared to other MBBs known so far. The challenge is to find a route for self-assembly of these cage hydrocarbons and their applications in the bottom-...
متن کاملThe CP110-interacting proteins Talpid3 and Cep290 play overlapping and distinct roles in cilia assembly
We have identified Talpid3/KIAA0586 as a component of a CP110-containing protein complex important for centrosome and cilia function. Talpid3 assembles a ring-like structure at the extreme distal end of centrioles. Ablation of Talpid3 resulted in an aberrant distribution of centriolar satellites involved in protein trafficking to centrosomes as well as cilia assembly defects, reminiscent of los...
متن کاملDendron-mediated self-assembly of highly PEGylated block copolymers: a modular nanocarrier platform.
PEGylated dendron coils (PDCs) were investigated as a novel potential nanocarrier platform. PDCs self-assembled into micelles at lower CMCs than linear copolymer counterparts by 1-2 orders of magnitude, due to the unique architecture of dendrons. MD simulations also supported thermodynamically favourable self-assembly mediated by dendrons.
متن کاملThe exocyst and regulatory GTPases in urinary exosomes
Cilia, organelles that function as cellular antennae, are central to the pathogenesis of "ciliopathies", including various forms of polycystic kidney disease (PKD). To date, however, the molecular mechanisms controlling ciliogenesis and ciliary function remain incompletely understood. A recently proposed model of cell-cell communication, called "urocrine signaling", hypothesizes that a subset o...
