Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

Advanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction

Fe‐Photocatalyzed Decarboxylative Giese‐Type Reaction of α‐N, O or S Carboxylic Acids: Insight into the Mechanism of the Radical Formation

Advanced Synthesis &Catalysis, EarlyView.
Electron‐deficient alkenes can be functionalized with α‐amino, α‐alkoxy and α‐alkylthio radicals formed by Fe‐photocatalyzed decarboxylation of the corresponding carboxylic acids. The reactions proceed under smooth ligandless conditions with inexpensive base and in the absence of oxidant. A mechanistic computational TD‐DFT study supports the occurrence

Do early‐treated adults with phenylketonuria sense high phenylalanine levels?

JIMD Reports
This study aimed to analyze whether early‐treated adults with phenylketonuria (PKU) can subjectively sense high phenylalanine (Phe) concentrations and whether a possible impact of Phe on objective measures of cognitive performance and mood reflects ...

Polybithiophene‐Based Molecularly Imprinted Polymers: A Comparative Mechanistic Study on Electrochemical Signal Transduction Approaches for Protein Detection

Advanced Sensor Research, EarlyView.
This study provides the first detailed comparison of the mechanisms behind differential pulse voltammetry and electrochemical impedance spectroscopy in electropolymerized molecularly imprinted polymer (MIP) sensing platforms. Using cystatin C as a model protein, it reveals how electron transfer processes generate signals and offers evidence‐based ...

A Phenylalanine Ammonia Lyase Capacitive Sensor for Phenylalanine Detection

Eurosensors 2023
In this paper, an easy-to-use and fast biosensor for phenylalanine quantification in patients affected by phenylketonuria is investigated. The phenylalanine concentration was indirectly estimated through the ammonia released as a by-product of an enzymatic reaction, which was then detected by exploiting an yttria-stabilized zirconia layer deposited ...

Hemp Proteins Conjugated with Green Tea Polyphenol Extract Form De Novo Plant‐Sourced Emulsifiers Suitable for Nanodelivery Systems Bearing Lipophilic Psychopharmaceuticals

Advanced Therapeutics, EarlyView.
Green tea polyphenols, conjugated either covalently or non‐covalently to hemp protein, comprise an excellent stabilizing matrix for oxidatively‐sensitive small molecules. These nanoemulsions are highly stable to a variety of chemical and physical stressors, protecting the small molecule while allowing for easy uptake across cell membranes and rapid ...

A Study on the Cell Layer Patterns of a Citrus Periclinal Chimera Reveals β‐Cryptoxanthin Regulation in Citrus Fruits

Advanced Science, EarlyView.
Researchers have identified a citrus chimera with distinctive tissue origins and carotenoid profiles. It is discovered that fruit tissues develop from all three cell layers but in different proportions. A key transcription factor, MYB107, regulates β‐cryptoxanthin production by directly activating carotenoid biosynthesis genes, explaining why some ...
