Thermometric Based‐Microswimmers with Chemical and Optical Engines

Advanced Intelligent Systems, EarlyView.
Temperature sensing at small scales is typically performed using passive luminescent particles. Here, an alternative approach is demonstrated by integrating upconversion thermometry into self‐propelled microswimmers powered by chemical fuels or light. This strategy offers a step toward dynamic thermal sensing at the microscale, relevant to both lab‐on ...

Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma

Advanced Intelligent Systems, EarlyView.
A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

Inhibition and Formation of Amyloid Fibrils in the Bulk and at the Interface of Biomolecular Condensates

Angewandte Chemie, EarlyView.
In this review, we discuss how biomolecular condensates can inhibit amyloid aggregation in their interior, while still facilitating fibril formation at the interface between the dense and dilute phases, where molecular and mesoscale properties are likely optimal to promote protein aggregation.

Field‐Programable Dynamics in a Soft Magnetic Actuator Enabling True Random Number Generation and Reservoir Computing

Advanced Intelligent Systems, EarlyView.
Complex dynamics, often avoided in electromechanical design, can enhance soft robotics. We develop durable magnetic soft actuators operating in tunable dynamic regimes, enabling random number generation, stochastic computing, and time‐series prediction.

Asymmetric Iron‐Catalyzed Vicinal C(sp3)─H Diamination of Carboxylic Acids

Angewandte Chemie, EarlyView.
An iron‐catalyzed vicinal α,β‐C(sp3)─H diamination of readily available carboxylic acids furnishes chiral α,β‐diamino acids in a single pot with high regio‐, diastereo‐, and enantioselectivity (up to >20:1 dr and >99% ee). ABSTRACT The direct construction of chiral 1,2‐diamines through the stereoselective functionalization of two vicinal C(sp3)─H bonds

Relapses, Comorbidities, and Predictors of Outcome in Anti‐GABAA Receptor Encephalitis

Annals of Neurology, EarlyView.
Objectives To characterize the magnetic resonance imaging (MRI) lesion dynamics, comorbidities, predictors of relapse, and outcomes in anti‐γ‐aminobutyric acid type A receptor (GABAAR) encephalitis, and assess the utility of LIM‐domain‐only‐protein 5 (LMO5) antibodies as tumor markers.

Light and Dark Cycles Control the Structural Evolution of Photoresponsive Supramolecular Systems

Angewandte Chemie, EarlyView.
Here, we report a photoswitchable synthetic peptide that, under light energy cycles, exhibits supramolecular polymorphism coupled to darkness‐driven structural self‐selection. We demonstrate that light sustains a transient assembled state in the form of helical nanoribbons, hindering the system from undergoing a transition to the disassembled state ...
