Abstract

DNAzymes have gained various applications in scientific fields, but their practical uses in everyday life are still being investigated. Hair dyeing, a popular cosmetic practice, still poses potential health risks, owing to the toxicity of commercial hair dyes. In this study, we assessed the feasibility of DNAzyme-catalyzed hair dyeing using natural pigments. We found that DNAzymes of peroxidase activity can expedite dopamine polymerization, resulting in the black coloration of human hair in around half an hour. This process can be achieved by using the milder Tris buffer to substitute the NH₄OH with 0.1 mM H₂O₂. In addition, these DNAzymes can catalyze the polymerization of other natural pigments. Thus, our mild and rapid hair dyeing approach has the potential to substitute traditional harsh hair dyeing conditions and also provides new insights into the field of DNAzyme applications.

基于dnazyme催化的多巴胺氧化和天然色素染发

DNAzymes在科学领域得到了各种各样的应用，但它们在日常生活中的实际用途仍在研究中。染发是一种流行的美容做法，由于商业染发剂的毒性，仍然存在潜在的健康风险。在本研究中，我们评估了dnazyme催化天然色素染发的可行性。我们发现过氧化物酶活性的DNAzymes可以加速多巴胺聚合，导致人类头发在大约半小时内变黑。这个过程可以通过使用温和的Tris缓冲液用0.1 mM的H2O2代替NH4OH来实现。此外，这些DNAzymes还可以催化其他天然色素的聚合。因此，我们的温和和快速染发方法有可能取代传统的恶劣染发条件，也为DNAzyme应用领域提供了新的见解。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
