01Overview and value chain

Markers: [EC: Advanced Laboratory Automation & Robotics | OECD: biotech-health | Regulator: FDA (US), EMA (EU), NMPA (China)]

Lab automation and wet-lab robotics represent the technological foundation of the modern bioeconomy, transitioning biological research from a manual, artisanal format to industrial, high-throughput scale. The integration of precision robotic arms, liquid handling workstations, multi-modal sensors, and control software enables the end-to-end automation of routine laboratory operations, including pipetting, centrifugation, thermocycling, and signal detection. Automated liquid handling systems equipped with up to 384-channel pipetting heads can dispense volumes ranging from 0.5 microliters to 5 milliliters with less than 1 percent error. By completely removing human error and fatigue, these robotic systems exponentially accelerate R&D timelines, allowing facilities to execute High-Throughput Screening (HTS) of up to a million chemical compounds or engineered enzyme variants in a single day. The deployment of standardized, AI-driven “self-driving labs” further ensures that the most complex biological protocols are globally reproducible.

The key directions of lab automation & wet-lab robotics are:

1. Automated Liquid Handling: Deploying high-precision robotic pipetting workstations with independent pressure monitoring to transfer nanoliter to milliliter volumes flawlessly.
2. Acoustic Dispensing: Utilizing focused ultrasound waves (e.g., Echo systems) to eject 2.5-nanoliter droplets without physical contact, entirely eliminating tip waste and cross-contamination.
3. Digital Microfluidics (DMF): Manipulating isolated droplets on an electrode grid via electrowetting, enabling programmable, channel-free execution of miniaturized PCR and ELISA protocols.
4. Self-driving Labs: Integrating robotic platforms with closed-loop artificial intelligence and Bayesian optimization algorithms to autonomously design, execute, and analyze successive experiments.

06Tech stack and innovations

Modern wet-lab robotics are defined by extreme mechanical precision and tightly integrated, closed-loop analytical software.

1. Air-Displacement Pipetting:
   • Independent channels utilize high-resolution pressure sensors to monitor the aspiration and dispensing of liquids in real-time, instantly detecting anomalies like clots or empty wells.
   • Proprietary conductive and capacitive liquid level detection ensures the pipette tip barely breaches the surface, preventing sample carryover and external contamination.
2. Acoustic Droplet Ejection (ADE):
   • Transducers emit highly focused bursts of acoustic energy into a fluid reservoir, ejecting precisely 2.5-nanoliter droplets upwards into an inverted target microplate.
   • By eliminating disposable plastic tips and capillaries, ADE prevents cross-contamination and dramatically reduces plastic waste and reagent costs.
3. Electrowetting-on-Dielectric (EWOD):
   • Digital microfluidics applies electrical potentials across a grid of insulated electrodes to alter the hydrophobicity of the surface, dragging nanoliter droplets across a PCB.
   • Allows complex, programmable assay protocols to be executed on a compact cartridge without the need for pumps, valves, or moving mechanical parts.

Stage 1: Assay digitization

Translating a manual biological protocol into a machine-readable Python script or graphical drag-and-drop workflow specifying exact volumes, incubation times, and labware coordinates.

Stage 2: Deck preparation

An operator or robotic arm loads the automated workstation deck with the required disposable tips, reagent troughs, microplates, and deep-well reservoirs.

Stage 3: Library dilution

The 96-channel liquid handling arm aspirates source chemical compounds and performs precise serial dilutions across multiple intermediate microplates to establish concentration gradients.

Stage 4: Acoustic transfer

An Echo acoustic dispenser rapidly transfers 2.5-nanoliter droplets of the diluted compounds and biological targets into high-density 1536-well assay plates without physical contact.

Stage 5: Automated reading

A robotic manipulator arm retrieves the sealed assay plates from the incubation module and loads them into a multi-mode microplate reader to capture fluorescence or luminescence signals.

Stage 6: AI data processing

The raw spectroscopic data is streamed to an integrated cloud platform where machine learning algorithms evaluate hit candidates and automatically calculate the pipetting map for the next screening iteration.
