The power of the incredibly small is all around you.
Imagine a world where doctors can deploy microscopic particles to precisely target and destroy cancer cells, where materials can repair their own scratches, and where clean energy is harnessed with unprecedented efficiency.
This isn't science fiction—it's the reality being built in laboratories today through nanotechnology. In 2017, a pivotal gathering of brilliant minds at the NANO 2017 conference set the stage for breakthroughs that are now beginning to transform our lives. This international conference, which attracted over 800 scientists from approximately 25 countries, served as a catalyst for innovations that manipulate matter at the scale of individual atoms and molecules 1 .
To grasp the significance of nanotechnology, consider this: a nanometer is one-billionth of a meter. At this scale, ordinary materials exhibit extraordinary properties. Gold can appear red or purple; carbon becomes stronger than steel yet remains incredibly light; and substances that couldn't conduct electricity might become superconductors.
The NANO 2017 conference, organized by the Institute of Physics of NAS of Ukraine with participation from prestigious institutions across Europe, showcased research across diverse fields including nanobiotechnology, nanocomposites, nanooptics, and nanostructured surfaces 1 .
What united these varied disciplines was a common focus on understanding and manipulating the unique phenomena that occur at this scale, where the classical laws of physics transition into the strange world of quantum mechanics.
As one special issue later described it, the "real nano-revolution refers to the ability to intervene and model matter at the nano-dimension rather than to just describe it in this realm" 2 . Scientists are no longer mere observers of the nanoscale—they've become architects, designing and building structures with atomic precision.

One compelling example of nanoscale innovation presented in NANO 2017-related research involves creating stealth nanoparticles for medical applications. Let's explore a key experiment that addresses a critical challenge in nanomedicine: how to deliver therapeutic agents without triggering the body's immune response.
Virus-like nanoparticles (VLNPs) show tremendous promise as drug delivery vehicles due to their perfect size and structure. However, our immune systems naturally recognize and eliminate these particles, just as they would a real virus.
The scientific team asked a bold question: Could they make these viral particles "invisible" to our immune system?
Their ingenious solution was to shield hepatitis B core antigen (HBcAg) VLNPs with a biocompatible polymer called poly(2-ethyl-2-oxazoline) (PEtOx) 2 . This hydrophilic (water-attracting) polymer forms a protective cloud around the nanoparticle, effectively disguising it from the immune system's detection mechanisms.
Researchers first created amine-functionalized PEtOx (PEtOx-NH₂) using a precision technique called living cationic ring-opening polymerization, which allows exact control over the polymer's size and structure 2 .
The team chemically attached these PEtOx polymers to the surface of the HBcAg virus-like nanoparticles through covalent bonds, specifically targeting carboxyl groups on the nanoparticle's surface 2 .
The shielded nanoparticles were tested in Tris-buffered saline at human body temperature (37°C/98.6°F) for five days to confirm they maintained their structural integrity under physiological conditions 2 .
Using enzyme-linked immunosorbent assays (ELISA), researchers quantified how effectively the polymer shielding reduced the nanoparticles' recognition by immune cells compared to unshielded nanoparticles 2 .
The experiment demonstrated that PEtOx-conjugated HBcAg nanoparticles maintained excellent stability while showing significantly reduced antigenicity—meaning they were far less likely to trigger an immune response 2 .
This breakthrough has profound implications. By creating these "stealth" nanocarriers, scientists can now envision:
Reduction in immune recognition
