Janus nematic colloids

, 2009
We study the behavior of Janus colloidal particles in the nematic liquid crystal 5CB using polarizing optical microscopy and Landau-de Gennes (LdG) modeling.

Engineering synthetic cells with intramembrane domains possessing distinct bilayer asymmetries

Nature Communications
Our understanding of how membrane asymmetry governs biological function is limited by the lack of techniques to produce model membranes which can reliably and accurately mimic cellular membrane asymmetry.

MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

Advanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Bacterial‐Electrochemical Platform Utilizing a MXene‐Peptide Hydrogel

Advanced Functional Materials, EarlyView.
A peptide‐based fibrillar hydrogel incorporating MXene facilitates efficient electron delivery to intracellular recombinant [FeFe]‐hydrogenase enzyme in E. coli, enabling sustained bioelectrochemical H2 production without engineered exoelectrogenicity pathways.

Catalytic Self-Phoretic Active Colloids [PDF]

, 2017
Active Janus colloids are nano to micron sized colloids, capable of propelling themselves through fluidic environments. Localised, asymmetric catalytic reactions on the colloidal bodies are used to decompose a dissolved ‘fuel’ to produce motion.

Fluorescence-based mapping of condensate dielectric permittivity uncovers hydrophobicity-driven membrane interactions

Nature Communications
Biomolecular condensates, essential for cellular organization, possess mesoscale properties largely governed by hydrophobicity, influencing molecule partitioning and material characteristics like viscosity, surface tension, and hydration.

Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids

Advanced Functional Materials, EarlyView.
Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.
