Operating at the scale of trillionths of a meter, picotechnology is enabling breakthroughs from targeted cancer therapies to historical preservation
Imagine technology so precise it could place individual atoms into specific positions, or manipulate materials on a scale a thousand times smaller than the most advanced nanotechnology available today.
This is the promise of picotechnology—the next great frontier in material science and engineering. While nanotechnology operates at the scale of billionths of a meter, picotechnology functions at the realm of trillionths of a meter, approaching the scale of individual atoms. In this invisible realm, materials exhibit extraordinary properties that defy our everyday understanding of physics and chemistry.
Across research laboratories worldwide, scientists are harnessing these unique capabilities to develop revolutionary solutions to some of humanity's most pressing challenges in medicine and environmental protection.
The emergence of picotechnology represents a paradigm shift in scientific capability. As research pushes beyond the nanoscale, scientists are discovering that pico-size particles could brighten scientists' view to new research fields, opening up unprecedented opportunities for innovation 1 .
From targeted cancer therapies that operate with cellular precision to diagnostic systems that detect diseases at their earliest molecular beginnings.
Environmental restoration techniques that protect historical monuments at the molecular level and precision conservation techniques for ecosystems.
To comprehend the revolutionary potential of picotechnology, we must first grasp the almost unimaginably small dimensions at which it operates. While nanotechnology deals with structures measuring 1 to 100 nanometers (where a nanometer is one billionth of a meter), picotechnology functions at the picoscale—1 to 100 picometers. A picometer is one trillionth of a meter, a scale so minute that it approaches the size of individual atoms.
To visualize this scale, consider that a single water molecule measures approximately 95 picometers across. At this level, the classical physics of our everyday experience begins to blur with the strange rules of quantum mechanics, granting materials extraordinary new capabilities.
One of the most practical applications of pico-scale principles already transforming laboratories is picoliter dispensing. This technology enables the precise handling of liquid volumes as small as 10 picoliters—a volume so minute it would take 50,000 such droplets to equal a single microliter, which itself is already invisible to the human eye. To visualize this incredible scale, a 10 picoliter droplet is roughly equivalent to just three red blood cells arranged end-to-end 4 .
Modern picoliter dispensers achieve accurate repeated dispensing of volumes as low as 10 picoliters, enabling researchers to work with unprecedented exactness 4 .
The ability to dispense tiny droplets enables high-density sample arrays, maximizing data output while conserving often precious or expensive reagents.
Beyond conventional liquid handling, researchers have developed remarkable picodroplet technology that creates picoliter-volume aqueous droplets suspended in carrier oil. Each microscopic droplet functions as an individual microscopic test tube, allowing scientists to conduct millions of parallel experiments simultaneously 9 . This approach has revolutionized synthetic biology by accelerating the "build-test-learn" cycle essential to engineering biological systems.
The technology enables researchers to evaluate large libraries of biological constructs quickly and confidently, dramatically speeding the development timeline for new biological solutions.
The extraordinary capabilities of picoscale particles allow scientists to overcome conventional obstacles that have long limited scientific progress. As researchers fabricate increasingly sophisticated pico-scale particles and develop complementary pico-technology, many believe we are approaching a breakthrough in biomedicine comparable to the revolution sparked by nanotechnology several decades ago 1 .
Historical brick buildings around the world face constant degradation from environmental factors—water infiltration, temperature fluctuations, pollution, and wind-driven particles gradually erode these cultural treasures. Traditional restoration methods often prove inadequate or require invasive interventions that can damage the original materials.
Seeking a better solution, a research team turned to picotechnology to develop a protective treatment that could penetrate and protect historical brick at the molecular level without altering its appearance 7 .
The researchers designed an elegant experiment to test the effectiveness of montmorillonite nanoclay spray—a form of nano-pico technology—for protecting historical bricks. The step-by-step procedure illustrates the precision possible with modern picotechnology:
Researchers collected historical brick samples from Mehmandoost Tower, a Seljuk-era structure in Iran dating back to 490 AD, along with new handmade bricks for comparison 7 .
The team prepared a treatment solution containing montmorillonite K10 nanoclay with particle sizes between 1-2 nanometers (approaching the picoscale) suspended in ethanol solvent. Multiple concentrations (2-10%) were tested to determine optimal effectiveness 7 .
Using a specialized spraying system, researchers applied the nanoclay solution evenly across the brick surfaces. The approach was classified as a "green and sustainable spray technique" due to its environmental compatibility .
Treated samples underwent battery of tests including water absorption measurements, porosity analysis through Brunauer-Emmett-Teller (BET) method, field emission scanning electron microscopy (FESEM), and accelerated aging tests to simulate long-term environmental exposure 7 .
The experiment yielded compelling evidence for the effectiveness of picotechnology in cultural heritage preservation. The treatment successfully filled microscopic pores and capillary cracks in the brick structure, creating a protective barrier that significantly reduced water penetration while maintaining the material's ability to "breathe"—a crucial requirement for historical masonry that must absorb and release moisture with changing humidity levels 7 .
Perhaps most impressively, the nanoclay treatment demonstrated an optimal balance between reducing damaging water absorption while maintaining sufficient vapor permeability. As the researchers noted, "Using nanoclays as Nano-Pico Geotechnics (NaPG) and Nano-Geotechnics (NaG) techniques can consider the balance between reducing water absorption and maintaining sufficient vapor permeability (breathability)" 7 . This balance is crucial for historical preservation, as completely sealing masonry materials often leads to new forms of degradation.
Accelerated aging tests further confirmed the long-term stability of the treatment, showing that properly applied nanoclay spray could provide protection for extended periods without needing reapplication. The research team concluded that this approach represented a viable, minimally invasive protective strategy for historic brick structures that could be adapted to various environmental conditions .

The emerging field of picotechnology represents more than just incremental scientific progress—it offers a fundamental shift in how we interact with the material world.
By operating at scales approaching individual atoms, researchers are developing solutions to challenges that have long resisted conventional approaches. From revolutionizing biomedical applications through graphene quantum dots that enable unprecedented precision in diagnostics and treatment, to protecting our cultural heritage through nanoclay sprays that preserve historical structures at the molecular level, picotechnology demonstrates extraordinary potential across diverse fields 1 7 .
As with any transformative technology, picotechnology will require careful consideration of ethical implications and potential unintended consequences. However, the current research trajectory suggests we are at the beginning of a revolution in capability that will blur the boundaries between biology and technology, between natural and engineered solutions.
The extraordinary abilities of pico-particles highlighted in early research are likely just the first glimpse of a technological landscape that will transform our approach to medicine, environmental protection, and material science in the decades ahead 1 . The invisible revolution of picotechnology is already beginning to visible change our world for the better.
