Shape programming of liquid crystal elastomers

Communications Chemistry, Journal Year: 2024, Volume and Issue: 7(1)

Published: March 14, 2024

Liquid crystal elastomers (LCEs) are shape-morphing materials that demonstrate reversible actuation when exposed to external stimuli, such as light or heat. The actuation's complexity depends heavily on the instilled liquid alignment, programmed into material using various shape-programming processes. As an unavoidable part of LCE synthesis, these also introduce geometrical and output restrictions dictate final applicability. Considering LCE's future implementation in real-life applications, it is reasonable explore limiting factors. This review offers a brief overview current methods relation challenges employing LCEs soft, shape-memory components devices.

Topical drug delivery strategies for enhancing drug effectiveness by skin barriers, drug delivery systems and individualized dosing

Frontiers in Pharmacology, Journal Year: 2024, Volume and Issue: 14

Published: Jan. 16, 2024

Topical drug delivery is widely used in various diseases because of the advantages not passing through gastrointestinal tract, avoiding irritation and hepatic first-pass effect, reaching lesion directly to reduce unnecessary adverse reactions. The skin helps organism defend itself against a huge majority external aggressions one most important lines defense body. However, skin’s strong barrier ability also obstacle effectiveness topical medications. Allowing bioactive, composition pass stratum corneum as needed reach target site essential need for exert its therapeutic effect. state barrier, choice system composition, individualized disease detection dosing planning influence Nowadays, enhancing transdermal absorption topically applied drugs hottest research area. first improve all drugs. Excessive enhances accumulation at non-target sites occurrence This paper introduces strategies from three perspectives: delivery, describes current status shortcomings research, provides new directions ideas research.
