Stem cell nano drug delivery applications to treat diabetes

Stem cell nano drug delivery applications to treat diabetes

Drug Delivery, Issue 2 2016 / 4 May 2016 / Vishal Shahidadpury, Anjali Hirani and Yashwant Pathak - University of South Florida Health

Stem cell therapy is currently utilised in medicine for its application in tissue repair and regenerative medicine. Unique characteristics of stem cells, such as self-renewal and differentiation, allow its function to be applicable for therapeutic purposes. Nanotechnology and cell microencapsulation have been researched and used as a means to protect cells from innate immune responses while permitting targeted drug delivery, as well as for sustained release of therapeutic agents to specific organs or cells. This review will provide an overview of stem cells, the purpose of nanotechnology and various surface modifications of nanoparticles for enhanced drug delivery, as well as describe how stem cell therapy is used for type 1 and type 2 diabetes mellitus. Additionally, a specific application of nanoparticle encapsulation and human embryonic stem cells in achieving glycaemic control, as seen in type 1 diabetes-induced immune-competent mice, will be discussed…

Nanotechnology tackles problems with noninvasive glucose monitoring

Nanotechnology tackles problems with noninvasive glucose monitoring

Drug Delivery, Issue 2 2016 / 4 May 2016 / Andreas Thomas, Medtronic GmbH / Araceli Ramírez and Alfred Zehe, Universidad Autónoma de Puebla

For diabetes mellitus patients who treat themselves with insulin, the need to self-monitor blood glucose in order to establish their insulin dose is a major burden, and highlights the need to develop non-invasive glucose measurement technologies. Up until now, such non-invasive systems that also have adequate measurement performance under daily life conditions have not been available. However, nanotechnology has the potential to provide a solution. Traversing all scientific disciplines its nanoscale nature means that new functionalities and properties of materials can be created, which contribute to the development of innovative products and applications. Nanomedicine extends from the medical applications of nanomaterials to nanoelectronic biosensors, and there are even possible future applications of molecular nanotechnology. Indeed, nanoparticles’ use in medicine is leaping ahead. For example, both organic and inorganic artificial nanoscale materials may be introduced into the human body and assigned diagnostic functions…

Polyelectrolyte complexes as nanoparticulate drug delivery systems

Polyelectrolyte complexes as nanoparticulate drug delivery systems

Issue 3 2015, Manufacturing & Packaging / 3 July 2015 / Anita Umerska, University of Anger and Lidia Tajber, Trinity College Dublin

Polyelectrolyte complexes at the nanoscale (polyelectrolyte complex nanoparticles; PECNs) can be harnessed as drug delivery systems for a range of low molecular weight drugs as well as peptides and proteins. The mild method of manufacture of PECNs results in the protection of the loaded bioactive and the choice of polyions forming the carrier makes PECNs very flexible in the design of a range of medical and pharmaceutical applications. This paper presents the key characteristics of PECNs and developments in the area…

Particle Resizing

Particle characterisation in drug delivery

Issue 4 2014, Manufacturing & Packaging / 5 September 2014 / Driton Vllasaliu and Ishwar Singh, University of Lincoln

The use of materials in nano-scale dimensions is proving to be a promising approach to overcome drug delivery challenges. ‘Nanomedicine’ technologies are gradually achieving commercial success and reaching the clinic. Sub-micron nanocarriers have the potential to ferry the therapeutic to its site of action and in this process overcome the biological barriers and achieve targeted drug delivery, controlled or stimuli-responsive delivery and protect the therapeutic from biological milieus. Many different types of nanocarriers have been described, including polymeric nanoparticles (NPs), liposomes, solid lipid NPs, micelles, dendrimers and metal NPs among other systems (the terms ‘nanomedicine’, ‘NP’ and ‘nanocarriers’ are used herein to describe all nanosystems). Of particular interest are nanocarriers with the ability to act selectively and target cell internalisation processes, guiding the therapeutic into subcellular regions. NP features important in dictating their drug delivery performance, including targeted delivery and cellular trafficking, are their size, shape and surface characteristics such as surface charge, chemistry and the distribution of ligands…
