RESUMO
Most of the treatment strategies for tumors and other disorders is photodynamic therapy (PDT). For several years, increasing the efficiency of nanostructured treatment devices, including light therapy, has been considered in different treatment methods. Light Dynamics The use of nanomaterial in this method's production and progress. The use of nanoparticles as carriers is a promising accomplishment, since all the criteria for an ideal photodynamic therapy agent can be given with these nanomaterials. The kinds of nanoparticles that have recently been used in photodynamic therapy are mentioned in this article. Latest advancements are being explored in the use of inorganic nanoparticles and biodegradable polymer-based nanomaterial as carriers of photosynthetic agents. Photosynthetic nanoparticles, self-propagating nanoparticles, and conversion nanoparticles are among the successful photodynamic therapy nanoparticles addressed in this report.
A maioria das estratégias de tratamento para tumores e outros distúrbios consiste na terapia fotodinâmica (PDT). Por vários anos, observou-se o aumento da eficiência de dispositivos de tratamento nanoestruturados, incluindo terapia de luz, que tem sido considerada em diferentes métodos de tratamento. Desse modo, este trabalho visa analisar a utilização de nanomateriais na produção e evolução deste método. A utilização de nanopartículas como carreadores é uma conquista promissora, pois todos os critérios para um agente de terapia fotodinâmica ideal podem ser obtidos com esses nanomateriais. Os categorias de nanopartículas que têm sido utilizados recentemente na terapia fotodinâmica são mencionados neste artigo. Os últimos avanços estão sendo explorados na utilização de nanopartículas inorgânicas e nanomateriais à base de polímeros biodegradáveis como portadores de agentes fotossintéticos. Nanopartículas fotossintéticas, nanopartículas autopropagantes e nanopartículas de conversão estão entre as nanopartículas de terapia fotodinâmica bem-sucedidas abordadas neste trabalho.

Metals, such as copper and silver, can be extremely toxic to bacteria at exceptionally low concentrations. Because of this biocidal activity, metals have been widely used as antimicrobial agents in a multitude of applications related with agriculture, healthcare, and the industry in general. A large number of microorganisms live in the human environment. if the balance of these creatures in nature is disturbed, the health of the individual and society will be threatened due to the production and emission of unpleasant odors and the reduction of health standards. The presence of microorganisms on textiles can cause adverse effects such as discoloration or staining on textiles, decomposition of fibrous materials, reduced strength, and eventually decay of textiles. Most fibers and polymers do not show resistance to the effects of microbes and by providing growth factors for microorganisms such as the right temperature and humidity, nutrients from sweat and fat from skin glands, dead skin cells as well as materials used in the stage of finishing the textiles causes the rapid growth and spread of various microbes. With the advent of nanotechnology, various industries and human daily life underwent changes. In recent years, increasing research on nanoparticles has led to the production of textiles with greater efficiency and added value. These modified textiles prevent the spread of unpleasant odors, the spread, and transmission of diseases. This article reviews the basics and principles of antimicrobial tetiles, as well as a brief overview of antimicrobial materials and nanostructures with antimicrobial properties.
Metais como cobre e prata podem ser extremamente tóxicos para bactérias em concentrações excepcionalmente baixas. Devido a esta atividade biocida, os metais têm sido amplamente utilizados como agentes antimicrobianos em uma infinidade de aplicações relacionadas à agricultura, saúde e indústria em geral. Muitos microrganismos vivem no ambiente humano e, se o equilíbrio dessas criaturas na natureza for alterado, a saúde dos indivíduos e da sociedade estará ameaçada devido à produção e emissão de odores desagradáveis e à redução dos padrões de saúde. A presença de microrganismos em têxteis pode causar efeitos adversos, como descoloração ou manchas, decomposição de materiais fibrosos, resistência reduzida e, eventualmente, deterioração. A maioria das fibras e polímeros não apresenta resistência aos efeitos dos micróbios e fornecem fatores de crescimento para os microrganismos, como temperatura e umidade adequadas, nutrientes do suor e gordura das glândulas da pele, células mortas da pele, bem como materiais usados na etapa de acabamento causando crescimento e disseminação de vários micróbios. Com o advento da nanotecnologia, diversas indústrias e o cotidiano humano passaram por mudanças. Nos últimos anos, o aumento da pesquisa em nanopartículas levou à produção de têxteis com maior eficiência e valor agregado. Esses têxteis modificados evitam a propagação de odores desagradáveis, a propagação e a transmissão de doenças. Este artigo analisa os fundamentos e princípios dos têxteis antimicrobianos, bem como uma breve visão geral dos materiais antimicrobianos e nanoestruturas com propriedades antimicrobianas.
