Diffusion-controlled hydrogel polymeric matrix devices have been among the most widely used drug delivery systems. How ever in homogeneous hydrogel the diffusional distance increase with time and hence, the release rate decreases. That results in high rele ...
Hydrogels are cross-linked, water-swollen polymer networks. Hydrogels with high mechanical and viscous dissipation properties are of great interest for mechanically control drug release systems. Since hydrogels are 3D polymer network with high amount of wa ...
Desorption processes of low-molecular-weight compounds from the surface of smectites into the gas phase determine a number of processes, e.g. those involved in drug delivery and the release of herbicides. The desorption has not been investigated thoroughly ...
Photodynamic therapy (PDT) is clinically-approved in the treatment of angiogenic disorders, particularly eye diseases such as age-related macular degeneration (AMD) and skin cancers, such as basal cell carcinoma. PDT causes vascular occlusion resulting in ...
Interfacing organic electronics with biological substrates offers new possibilities for biotechnology by taking advantage of the beneficial properties exhibited by organic conducting polymers. These polymers have been used for cellular interfaces in severa ...
HEMA hydrogels are hydrophobic biocompatible hydrogel with high mechanical and viscoelastic properties, which are widely used in biomedical application including drug delivery systems. The mechanical properties and permeability of these hydrogels can be tu ...
Separation of functional magnetic particles or magnetically labeled entities is a key feature for bioanalytical or biomedical applications and therefore also an important component of lab-on-a-chip devices for biological applications. We present a novel in ...
The trend towards personalized medicine and the long-standing wish to reduce drug consumption and unwanted side effects have been the driving force behind research on drug delivery vehicles that control localization, timing and dose of released cargo. Cont ...
We show that the binary logarithm of the nonnegative rank of a nonnegative matrix is, up to small constants, equal to the minimum complexity of a randomized communication protocol computing the matrix in expectation. We use this connection to prove new con ...
