Protein recovery from industrial microbial processes can be very expensive, often exceeding the cost of protein production. We have genetically engineered 3 beta-galactosidase (beta-gal) fusion proteins containing poly-aspartic acid tails to test the effect of the tails on recovery by

Insurmountable detection challenges will impede the development of many of the next-generation of lab-on-a-chip devices (e.g., point-of-care and real-time health monitors). Here we present the first membrane-based, microfluidic sample preconcentration method that is continuous, quantifiable, simple, and capable of working

Chronic imaging of neuronal networks in vitro has provided fundamental insights into mechanisms underlying neuronal function. Current labeling and optical imaging methods, however, cannot be used for continuous and long-term recordings of the dynamics and evolution of neuronal networks, as

An efficient purification of recombinant proteins often requires a high ratio of recombinant to host proteins. In plants, Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is the most abundant leaf protein, thus strongly impacting purification yield. Here, we describe a simple and robust purification

Novel Inks for Direct-Write Assembly of 3-D Periodic Structures

New methods for materials fabrication at the micro- and nanoscale will drive scientific and technological advances in areas of materials science, chemistry, physics, and biology. The broad diversity of potentially relevant materials, length scales, and architectures underscores the need for flexible patterning approaches. One important example is the fabrication of 3D periodic structures composed of colloidal, polymeric, or semiconductor5 materials.

Nanoparticle-Based Drug and Gene Delivery for Tumor Targeting

Professor Yoshiki Katayama (Kyushu University, Japan) discusses recent advances in drug delivery systems and strategies that exploit the EPR effect, with a special focus on stimuli-responsive systems based on novel materials.

Functionalized PEI and Its Role in Gene Therapy

Gene therapy has become one of the most discussed techniques in biomedical research in recent years.

Polyelectrolyte Multilayer Films and Membrane Functionalization

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
