Here we describe a simple method for patterning oxide-free silicon and germanium with reactive organic monolayers and demonstrate functionalization of the patterned substrates with small molecules and proteins. The approach completely protects surfaces from chemical oxidation, provides precise control over feature morphology, and provides ready access to chemically discriminated patterns.

Here, we present a protocol to make a bacterial nanocellulose (BNC) magnetic for applications in damaged blood vessel reconstruction. The BNC was synthesized by G. xylinus strain. On the other hand, magnetization of the BNC was realized through in situ precipitation of Fe2+ and Fe3+ ferrous ions inside the BNC mesh.

Columnar zinc oxide structures in the form of rods are synthesized via aerosol-assisted chemical vapor deposition without the use of pre-deposited catalyst-seed particles. This method is scalable and compatible with various substrates based on either silicon, quartz or polymers.
FAQs
Surface silanol groups provide reactive sites for attaching organosilanes. Hydrolysis first activates the organosilane, after which condensation forms covalent Si–O–Si linkages at the silica interface. This chemistry anchors the introduced groups rather than merely depositing them physically, helping determine how effectively the modified surface expresses its intended interfacial properties.
Moisture, solvent, and pH influence the balance between hydrolysis and condensation. These variables therefore affect how uniformly the coating forms and how stable it remains on the silicon oxide surface. Controlling them is important because an unsuitable combination can compromise coating quality, reducing the consistency of the resulting interfacial behavior.
The chemical groups attached to the surface can tune wettability, chemical selectivity, biocompatibility, and the availability of binding sites. These changes alter how the interface interacts with surrounding molecules or materials. Selecting different organic or inorganic groups therefore provides a way to adapt the same silicon oxide platform to distinct chemical and materials-science requirements.
The process commonly starts with the available surface silanol groups, followed by contact with an organosilane under conditions that support hydrolysis and condensation. Formation of Si–O–Si linkages then connects the introduced functionality to the surface. Moisture, solvent, and pH must be considered throughout because they influence the resulting coating quality and stability.
In sensors, tailored surface groups can provide binding sites or chemical selectivity, helping the interface interact preferentially with relevant species. In chromatography, modified interfacial chemistry can influence interactions during separation. These applications use the same surface-modification strategy for different analytical purposes: selective recognition in sensing and controlled chemical interactions in chromatographic systems.
Functionalized surfaces can supply chemically tailored interfaces for catalysis or provide binding sites for immobilizing biomolecules. The attached groups help establish the interactions needed at the solid surface while biocompatibility may be important for biological materials. This makes silicon oxide functionalization relevant when a stable, chemically designed interface is required.
