Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing UV-protective substances are not biocompatible, expensive, or have harmful side effects, and do not persist long enough to effectively absorb UV radiation, leading to damage in living and non-living materials.

Innovation Solution

Biological devices produced from microbial cells transformed with DNA constructs expressing UV-resistant proteins such as hexokinase, heat shock proteins, alcohol dehydrogenase, transferrin, flavonol synthase, and zinc or iron oxidases are used to create UV-resistant compositions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis
