The polymerase chain reaction is an immensely powerful technique for identification and detection purposes. Increasingly, competitive PCR is being used as the basis for quantification. However, sequence length, melting temperature and primary sequence have all been shown to influence the efficiency of amplification in PCR systems and may therefore… (More)
A cellular protease (furin)-mediated graphene-based nanosystem is developed for co-delivery of a membrane-associated cytokine (tumor-necrosis-factor-related apoptosis-inducing ligand, TRAIL) and an intracellular-acting small-molecule drug (Doxorubicin, DOX). TRAIL and DOX can be sequentially released toward the plasma membrane and nucleus, respectively.
A significant problem affecting electrospun nanofibrous tissue scaffolds is poor infiltration of cells into their three-dimensional (3D) structure. Environmental and physical manipulation, however, can enhance cellular infiltration into electrospun scaffolds. In this work, RGD-modified alginate mats with increased thickness and porosity were achieved by… (More)
