Crystalline Poly(L‐Lactic Acid) Nanoparticles via Nonsolvent‐Induced Cascade Phase Separation

Journal of Polymer Science, EarlyView.
Water is used as the nonsolvent to induce liquid/liquid phase separation (LLPS) of poly(L‐lactic acid) (PLLA)/propylene carbonate solution and PLLA crystallization. Due to the two levels of cascade LLPS coupled with confined PLLA crystallization, three types of polymeric nanoparticles, including PLLA single crystals, Ouzo crystalsomes, and sheaf‐like ...

Ambient, Bias‐Free, Green Nanoparticle Synthesis via Microdroplet‐Confined Galvanic Chemistry

Small, EarlyView.
Confined galvanic reactions within sprayed microdroplets drive the direct growth of metal nanoparticles on conductive surfaces under ambient conditions. Eliminating the need for external bias and thermal input, this approach offers a simple route toward more sustainable nanoparticle synthesis.

Near‐Armchair‐Enriched Growth of Single‐Walled Carbon Nanotubes via W‐Containing Fe‐Based Catalyst Systems in Mist FC‐CVD

Small, EarlyView.
A mist‐based floating catalyst chemical vapor deposition (mist FC‐CVD) strategy allows the use of non‐volatile precursors and multi‐component catalyst delivery in a continuous process. Through catalyst composition control, it generates near‐armchair‐enriched single‐walled carbon nanotubes (SWCNTs) and uncovers key factors governing chiral‐angle ...

A Pipette for High-Resolution Sampling and Delivery of pL Bio-Samples

Micromachines
Conventional laboratory methods for handling valuable biological samples typically use pipettes or needles, which are prone to issues such as dead volume and sample waste.

Programming Multidomain Peptides With Molecular Frustration Into Biomolecular Condensates

Small, EarlyView.
De novo designed multidomain peptides (MDPs) were used to explore how molecular ordering influences peptide phase behavior. MDPs containing partially folded β‐sheets were found to form biomolecular condensates. This work introduces a new design principle for condensate formation and expand the design space beyond conventional intrinsically disordered ...

Gravity‐Driven Assembly Dynamics of Liquid Metal Microdroplets for Functional Composite Films

Small, EarlyView.
This article presents a new understanding of the gravitational settling of liquid metal microdroplets in polymer resin films. It employs an experimental and analysis platform for quantification of the process‐structure relationships to inform the dynamics of gravity‐driven assembly in soft circuit architectures. ABSTRACT Liquid metal (LM) microdroplets

Topology‐Encoded Charge Polarity Governs Multiphase Organization in Intrinsically Disordered Protein Polymer Condensates

Small, EarlyView.
Electrostatic topology is shown to program phase separation and internal organization in thermoresponsive intrinsically disordered protein polymer (IDPP) condensates. By comparing oppositely charged IDPPs with a covalent diblock, chain connectivity is revealed to control charge compensation, dense‐phase micropolarity, miscibility, and apparent acid ...

Thermally Regulated Droplet Microfluidics Enables Uniform, Size‐Controllable DNA‐Nanoparticle Superlattices

Small, EarlyView.
Thermally regulated droplet microfluidics enables controlled assembly of DNA‐functionalized gold nanoparticles into uniform, size‐controllable superlattice crystals. Monodisperse droplets formed at elevated temperature suppress premature hybridization, followed by ultra‐slow cooling to promote near‐equilibrium growth.

Oxygen‐Tolerant Photo‐Induced Miniaturized Accelerated Atom Transfer Radical Polymerization (OPTIMA‐ATRP) for High‐Throughput Synthesis of Polymer Bioconjugates

Angewandte Chemie, Volume 138, Issue 33, 10 August 2026.
Oxygen‐tolerant photo‐induced miniaturized accelerated atom transfer radical polymerization (OPTIMA‐ATRP) in water was developed for the polymerization of hydrophilic (meth)acrylate monomers under ambient or sub‐ambient (4°C) temperature and atmospheric conditions, without prior degassing, in less than 10 min, at an ultra‐small scale (< 50 µL) in ...

Microdroplet Resuspension Off Surfaces

Langmuir
Understanding the resuspension of droplets from surfaces into air is important for elucidating a range of processes such as disease transmission of airborne pathogens and determining environmental contamination and the effectiveness of cleaning procedures. The resuspension condition is defined as the escape velocity of a droplet from a surface.
