Exploring the impact of nanoparticle design on Parkinson's disease therapies

NanoWerk.com - Tue, 03/19/2019 - 09:17
Alpha-synuclein is a protein whose function in the healthy brain is currently unknown. It is of great interest to Parkinson's researchers because it is a major constituent of Lewy bodies, protein clumps that are the pathological hallmark of Parkinson's disease (PD). Scientists believe that the self-assembly of ?-synuclein into oligomers and fibrils is linked to progress and pathogenesis of the disease. A new study suggest that important characteristics of the fibrillation process, such as surface charge and surface functional group, should be considered in the development of nanotechnology-based therapeutic approaches.

Molecular motors run in unison in a metal-organic framework

ScienceDaily.com: Nanotechnology News - Mon, 03/18/2019 - 22:11
For molecular motors to be exploited effectively, they need to be able to operate in unison. However, integrating billions of these nanometre-sized motors into a single system, and getting them to operate in unison has proved to be quite a challenge. Organic chemists have now succeeded in integrating numerous unidirectional light-driven rotary motors into a metal-organic framework (a solid material with a 3D cage-like structure).
