Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If monofunctional binders are used to bind nanoparticles, then the nanoparticle surface can be covered, but the complexes are not soluble in hydroalcoholic environments and cannot interact with bioactive functionalities
Solution Approach 1:
The binder molecule is divided into two distinct functional segments: a first functional group that binds to the nanoparticle surface and a second functional group that provides solubility in hydroalcoholic environments and enables interaction with bioactive molecules. This segmentation allows each part to perform its specific function independently, resolving the contradiction between surface coverage and bioactivity compatibility.
Solution Approach 2:
The binder is designed as a multifunctional molecule that simultaneously performs multiple functions: binding to the nanoparticle surface, providing solubility in hydroalcoholic environments, and enabling interactions with bioactive functionalities. This multi-functionality eliminates the need for separate components and directly addresses the limitation of monofunctional binders.
2Ease of manufacture
If simple aliphatic chains are used as binders, then the binding process is simple, but the chains cannot interact with functionalities present in bioactive molecules
Solution Approach 1:
The binder structure is segmented into a binding portion (first functional group) that maintains simplicity for nanoparticle attachment and a functional portion (second functional group) that provides specificity for interacting with bioactive molecules. This segmentation preserves the ease of binding while enabling sophisticated biological interactions.
Solution Approach 2:
Different parts of the binder molecule have different chemical properties: the first functional group is optimized for binding to the nanoparticle surface, while the second functional group is optimized for interacting with bioactive functionalities. This local differentiation of properties allows the binder to perform both simple binding and specific biological interactions.
3Device complexity
If monofunctional binders are used, then the complex formation is straightforward, but the complexes lack solubility in hydroalcoholic environments
Solution Approach 1:
The binder is designed as a universal molecule that inherently provides both binding capability and hydroalcoholic solubility through its dual functional groups. This multi-functionality simplifies complex formation while ensuring solubility, eliminating the need for separate solubility enhancement steps.
Solution Approach 2:
The chemical parameters of the binder are modified by introducing a second functional group with specific solubility characteristics. This parameter change enables the binder to provide hydroalcoholic solubility while maintaining binding functionality, thus resolving the solubility issue without complicating the formation process.
