Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Synthesis and stereochemical determination of diunsaturated valproic acid analogs including its major diunsaturated metabolite.

Journal of Lipid Research, 1985
Valproic acid, an antiepileptic drug, is transformed into diunsaturated metabolites in humans. Synthesis of the geometric isomers of 2-(1'-propenyl)-2-pentenoic acid and 2-(1'-propenyl)-3-pentenoic acid was attempted using known procedures.

Rational Control of Antibody Orientation for Enhancing Sensitivity and Specificity in Lateral Flow Immunoassays With Clinical Validation

Advanced Healthcare Materials, EarlyView.
Systematic investigation of antibody orientation strategies in lateral flow immunoassays reveals that a para‐substituted (aminomethyl)phenylboronic acid mediated probe (P‐6) combined with a biotin‐streptavidin test‐line modification achieves a synergistic 14‐ to 19‐fold sensitivity gain over conventional conjugation. Furthermore, multiplexed detection,
