The invention relates to a copolymer exhibiting both antimicrobial and anti-adhesive properties as well as to a hydrogel. Said hydrogel is obtained from the inventive copolymer and a substrate. Another part of the invention is a process for making the hydrogel, as well as different uses of the inventive copolymer as well as of the hydrogel.
The present invention relates to the use of imidazolium alkyl(meth)acrylate homo- and copolymers in cosmetic preparations and to the corresponding cosmetic preparations.

The object of the present invention is to provide a light absorptive compound which is capable of selectively absorbing light around a wavelength of 400 nm, and is excellent in solubility in various solvents and/or affinity with hydrophobic substances. Also, the object of the present invention is to provide an optical film containing such a light absorptive compound, and a cured layer. A compound represented by the following formula (I):
which may not be suitable for certain types of cancers, especially for treatment in vivo. To meet this need, we have constructed a multifunctional aptamer-based DNA nanoassembly (AptNA) for targetedcancer therapy. In particular, we first designed various Y-shaped functional DNA domains through predesigned base pair hybridization, including targeting aptamers, intercalated anticancer drugs, and therapeutic
通过 DNA/RNA 纳米技术将一维 DNA 构建块自组装成二维和三维纳米结构的能力已导致在生物成像、基础生物机制研究、疾病诊断和药物输送方面的广泛应用。然而,大多数核酸纳米结构的细胞摄取依赖于被动传递或增强的渗透性和滞留效应,这可能不适用于某些类型的癌症,尤其是体内治疗。为了满足这一需求,我们构建了一种多功能的基于适配体的 DNA 纳米组装 (AptNA),用于靶向癌症治疗。特别是,我们首先通过预先设计的碱基对杂交设计了各种 Y 形功能性 DNA 结构域,包括靶向适体、嵌入的抗癌药物和治疗性反义寡核苷酸。然后,这些功能性 DNA 域通过功能域和连接器臂中的互补序列连接到 X 形 DNA 核心连接器,称为构建单元。最后,数百(~100-200)个带有 5' 丙烯酸酯基团修饰的基本构建单元被进一步光交联成多功能和可编程的基于适配体的纳米组装结构,能够利用简单的模块化设计和组装,高可编程性、优
