Affinity Purification of RNA: Sequence-Specific Capture by Nonionic Morpholino Probes

BioTechniques, 1997
Nucleic acid isolation for amplification-based diagnostics requires techniques that do not co-purify inhibitors of DNA polymerases. Also, other requirements for an ideal sample preparation technology include ease of use, capability for automation, high ...

High‐Throughput Microfluidic‐Mediated Assembly of Layer‐By‐Layer Nanoparticles

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of polymer films on nanoparticle (NP) surfaces is a promising technique for targeted drug delivery. Despite its success in preclinical mouse models, a current good manufacturing practices (cGMP) compliant, clinical‐scale production method has been lacking.

Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

Advanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...

Systematic Comparison of Commercial Uranyl‐Alternative Stains for Negative‐ and Positive‐Staining Transmission Electron Microscopy of Organic Specimens

Advanced Healthcare Materials, EarlyView.
Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

Tri‐Layered Bioactive Cutaneous Scaffold with Integrated Bioactive Metal Organic Frameworks to Promote Full‐Thickness Infected Diabetic Wound Healing: Multifaceted Therapeutic Strategies

Advanced Healthcare Materials, EarlyView.
The limitations of existing clinical treatments highlight the need for a more comprehensive strategy for addressing infected diabetic wounds. A tri‐layered scaffold is developed to deliver therapeutics loaded in CuBDC and ZIF‐8 MOFs that are tailored to the requirements of deep‐infected diabetic wounds.

A new formalism for calculation of the partition function of single stranded nucleic acids [PDF]

arXiv, 2005
A new formalism for calculation of the partition function of single stranded nucleic acids is presented. Secondary structures and the topology of structure elements are the level of resolution that is used. The folding model deals with matches, mismatches, symmetric and asymmetric interior loops, stacked pairs in loop and dangling end regions, multi ...
