The Mixture Lab

We build the labs that will discover tomorrow's formulations, today.

Automation, robotics, and machine learning applied to formulation science, electrochemistry, and advanced materials research.

Materials Science

Engineering matter at the molecular level for performance-driven applications.

Research Highlights

Our work sits at the intersection of automation, AI, and chemistry, building the infrastructure for formulation discovery at scale.

RAISE
Interfacial & Formulation Science

Interfacial Science

We built RAISE, a network of self-driving laboratories that uses an agentic system to predict and discover liquid-surface interfacial behaviour, such as wetting, spreading, and coverage. These properties are critical across agriculture, contact lenses, eye drop formulations, medical devices, personal care, and coatings.

Hydrogel synthesis and imaging
Materials Science

Soft material Discovery & Characterisation

We advance the discovery of polymeric soft materials and complex formulations by developing new formulation strategies and creating platforms that rapidly and autonomously characterize their properties, for applications in drug delivery, agriculture, and personal care.

Mitochondria — cellular energy structures targeted for transplantation therapy
Regenerative Medicine

Mitochondrial Medicine

We combine biomaterials engineering, high-throughput experimentation, and AI-guided formulation design to develop strategies that preserve the stability and function of isolated mitochondria, enabling more effective mitochondrial delivery and transplantation.

Automated electrochemical reactor system
Electrochemistry

Electrochemistry

We develop electrochemical technologies for critical mineral recovery through Fe³⁺ regeneration, hydrogen and NaOH co-production, and industrial wastewater treatment to enhance biodegradability, biogas production, and resource recovery.

PLM
Microstructure

Microstructure

Tools such as polarized light microscopy use birefringence to visualize the microstructures of soft materials. Understanding and controlling these structures enables the engineering of desirable formulation properties, including controlled release, stability, and flow behavior.

Automation

Self-Driving Labs Orchestration

We orchestrate self-driving laboratories into fully closed-loop systems, linking instruments, data, and decision-making through Bayesian optimisation and agentic AI to accelerate scientific discovery.
