    • Atmospheric water harvesting using functionalized carbon nanocones 

      Leivas, Fernanda Rodrigues; Barbosa, Marcia Cristina Bernardes (2023) [Artículo de periódico]
      In this work, we propose a method to harvest liquid water from water vapor using carbon nanocones. The condensation occurs due to the presence of hydrophilic sites at the nanocone entrance. The functionalization, together ...

    • Bioadhesive 3D-printed skin drug delivery polymeric films : from the drug loading in mesoporous silica to the manufacturing process

      The alliance between 3D printing and nanomaterials brings versatile properties to pharmaceuticals, but few studies have explored this approach in the development of skin delivery formulations. In this study, clobetasol ...

    • Caenorhabditis elegans as an alternative in vivo model to determine oral uptake, nanotoxicity, and efficacy of melatonin-loaded lipid-core nanocapsules on paraquat damage 

      Charão, Mariele Feiffer; Souto, Caroline; Brucker, Natália; Barth, Anelise; Jornada, Denise Soledade; Fagundez, Daiandra de Almeida; Ávila, Daiana Silva de; Eifler-Lima, Vera Lucia; Guterres, Silvia Stanisçuaski; Pohlmann, Adriana Raffin; Garcia, Solange Cristina (2015) [Artículo de periódico]
      Caenorhabditis elegans is an alternative in vivo model that is being successfully used to assess the pharmacological and toxic effects of drugs. The exponential growth of nanotechnology requires the use of alternative in ...

    • Chitosan gel containing polymeric nanocapsules : a new formulation for vaginal drug delivery 

      Frank, Luiza Abrahão; Sandri, Giuseppina; D'Autilia, Francesca; Contri, Renata Vidor; Bonferoni, Maria Cristina; Caramella, Carla; Frank, Alejandro Germán; Pohlmann, Adriana Raffin; Guterres, Silvia Stanisçuaski (2014) [Artículo de periódico]
      The vaginal route of administration is an alternative for several treatments for either local or systemic pharmacological effects. However, the permanence of a drug in this route represents a challenge for formulation ...

    • Evaluation of lipoic acid topical application on rats skin wound healing 

      Külkamp-Guerreiro, Irene Clemes; Souza, Marielly Nunes; Bianchin, Mariana Domingues; Isoppo, Mateus; Freitas, Joana Sachetti; Alves, João Alex; Piovezan, Anna Paula; Pohlmann, Adriana Raffin; Guterres, Silvia Stanisçuaski (2013) [Artículo de periódico]
      PURPOSE: To evaluate the effects of lipoic acid (thioctic acid) topical application on wound healing on rats skin, and the consequences of lipoic acid nanoencapsulation on this process. METHODS: The model used was the ...

    • Impactos da nanotecnologia na saúde : produção de medicamentos 

      Dimer, Frantiescoli Anversa; Friedrich, Rossana Barcellos; Beck, Ruy Carlos Ruver; Guterres, Silvia Stanisçuaski; Pohlmann, Adriana Raffin (2013) [Artículo de periódico]
      Several studies have described the benefits of nanoscience and nanotechnology (N&N) in different sectors such as agriculture, energy, environmental preservation, and public health. The rapid evolution of N&N can be shown ...

    • Ionic liquid intercalated V2O5 nanorods : synthesis and characterization 

      Krishnappa, Manjunath; Souza, Virgínia Serra de; Dupont, Jairton; Ramakrishnappa, Thippeswamy; Nagaraju, Ganganagappa (2015) [Artículo de periódico]
      In this work, ionic liquid (IL) intercalated V2O5 (IL-V2O5) nanorods have been synthesized through the IL-assisted hydrothermal method using imidazolium-based functionalized IL at 130°C for 3 days. The structure and ...

    • Lipid-core nanocapsules : mechanism of self-assembly, control of size and loading capacity 

      Jornada, Denise Soledade; Fiel, Luana Almeida; Condotta, Kelly Bueno; Gerent, Josepe Franco; Petzhold, Cesar Liberato; Beck, Ruy Carlos Ruver; Guterres, Silvia Stanisçuaski; Pohlmann, Adriana Raffin (2012) [Artículo de periódico]
