Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drug delivery methods face challenges in solubilizing water-insoluble therapeutic agents, limiting their application in medicine due to difficulties in dispersing these compounds in water, which is necessary for effective administration.
Innovation Solution
Functionalized nanodiamond particles are used to form complexes with therapeutic agents, enhancing their water solubility and enabling their dispersion in aqueous environments, while maintaining therapeutic efficacy and reducing toxicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water-insoluble therapeutic agents are used, then therapeutic efficacy is improved, but water solubility deteriorates
Solution Approach 1:
The patent uses nanodiamond particles as an intermediary carrier to bridge the gap between water-insoluble therapeutic agents and the aqueous biological environment. The nanodiamonds adsorb the hydrophobic drugs on their surface, forming a composite delivery system that enables water dispersibility while preserving drug efficacy
Solution Approach 2:
The invention creates a composite material system consisting of nanodiamond particles combined with therapeutic agents. This composite structure integrates the properties of both components: the nanodiamonds provide water dispersibility and biocompatibility, while the therapeutic agents provide the desired pharmacological effect
2Quantity of substance
If therapeutic agents are dispersed in water, then water solubility is improved, but therapeutic efficacy deteriorates
Solution Approach 1:
Nanodiamond particles serve as a mediator that allows therapeutic agents to be dispersed in water without direct contact between the hydrophobic drug molecules and the aqueous environment. The nanodiamond surface acts as a protective interface that maintains drug stability and efficacy while enabling water dispersibility
3Adaptability or versatility
If therapeutic agents are administered systemically, then treatment coverage is improved, but toxicity deteriorates
Solution Approach 1:
The patent segments the therapeutic agent into individual molecular units that are distributed across numerous nanodiamond particles. This segmentation allows for controlled release and reduced peak concentrations, thereby reducing toxicity while maintaining broad treatment coverage through systemic circulation
