The goal of this protocol is to show the assembly of a biomimetic nanomatrix (NM) with Janus base nanotubes (JBNTs) and fibronectin (FN). When co-cultured with human mesenchymal stem cells (hMSCs), the NMs exhibit excellent bioactivity in encouraging hMSCs adhesion.

We present a protocol to synthesize Janus microhydrogels composed entirely of the same base material, poly(N-isopropylacrylamide) (PNIPAAm), with a clearly compartmentalized structure base on the phase separation of a supersaturated NIPAAm monomer solution. The synthesized Janus microhydrogels show unique properties such as anisotropic thermo-responsiveness and organophilic/hydrophilic loading capability.

Surface properties of a nanoparticle are important for their interaction with the surrounding medium. Therefore the surface modification of carbon nanotubes can be critical for their transport and retention through porous media. Here, lab scale column experiments are used to understand the possible transport and retention of these nanoparticles.
FAQs
Complementary hydrogen bonding and base stacking organize the molecular building blocks into an elongated arrangement. These noncovalent interactions collectively stabilize the association of neighboring units, allowing a hollow tubular architecture to emerge rather than an unstructured aggregate. In bioengineering, this cooperative assembly is important because it links molecular recognition between building blocks with the formation of a functional nanoscale structure.
The two differentiated faces create chemical asymmetry across the nanotube surface. That asymmetry can provide distinct interaction sites for molecular recognition, cargo binding, or contact with biological interfaces. Instead of presenting a uniform exterior, the structure offers chemically differentiated regions whose arrangement may help connect the nanotube's architecture with selective behavior in bioengineering systems.
Formation occurs under suitable solution conditions that allow hydrogen bonding, base stacking, and other noncovalent interactions to act together. If those interactions do not organize the molecular units effectively, the desired elongated hollow architecture may not develop. Controlling the assembly environment therefore matters for obtaining the intended nanotube structure and its associated binding or recognition properties.
A conceptual workflow begins with molecular building blocks that contain complementary recognition features and chemically distinct faces. The units are placed under solution conditions that support their noncovalent association, where hydrogen bonding and base stacking guide organization into elongated hollow tubes. The resulting architecture can then be considered for cargo binding, molecular recognition, or interaction with biological interfaces.
Their chemically differentiated surfaces can support selective molecular recognition and cargo binding, while the internal cavity provides a nanoscale space associated with the tubular architecture. These features make the platform relevant to biosensors, where selective interactions are useful, and to targeted delivery systems, where binding and biological-interface interactions may help connect the nanostructure with a desired bioengineering function.
They provide a model for studying programmable biomolecular materials whose structure arises from designed noncovalent interactions. Their combination of nanoscale dimensions, hollow interiors, and chemically distinct surfaces connects molecular self-assembly with engineered biological functions. This makes them useful for investigating how recognition, cargo association, and biological-interface interactions can be integrated into engineered nanostructures.
