Soft matter from liquid crystals

YK Kim, JH Noh, K Nayani, NL Abbott - Soft Matter, 2019 - pubs.rsc.org
Liquid crystals (LCs) are fluids within which molecules exhibit long-range orientational
order, leading to anisotropic properties such as optical birefringence and curvature elasticity …

Membrane proteins in action monitored by pH-responsive liquid crystal biosensors

P Bao, K Phillips, R Raval - ACS Applied Materials & Interfaces, 2024 - ACS Publications
