Peptide Terminated Polymer Brush Nanomaterials for Label‐Free Separation of Cancer Cells Based on Relative Adhesion

Small, EarlyView.
Horan et al. demonstrate that RGD peptide‐functionalized poly(ethylene glycol) brush films synthesized in polydimethylsiloxane microfluidic channels by surface‐initiated atom transfer radical polymerization enable label‐free separation of melanoma and ovarian cancer cells based on differential integrin expression.

The quartz crystal microbalance

, 2011
Quartz crystal resonators are among the most popular acoustic sensor devices. In this chapter we discuss the basic principles of the quartz crystal microbalance (QCM) technique and review current approaches to analyzing QCM measurements.

Thermal Instability Pathways of Aluminum‐Based Nanocomposites: The Role of Alloying‐Element‐Driven Precipitation and Amorphous Interlayers

Small, EarlyView.
Thermal instability mechanisms governing novel Al‐based PVD/ALD nanocomposites are uncovered through synchrotron XRD, STEM, APT, and micromechanical testing. Temperature‐dependent crystallite evolution reveals a defined stability window before degradation dominates, offering new insight into the design of thermally robust, functional Al‐based ...

Development of a QCM (Quartz Crystal Microbalance) Biosensor to the Detection of Aflatoxin B1

Open Journal of Applied Biosensor, 2013
In this study, we have used a direct immunoassay where the simple binding between antigen and an antibody is detected. Immunoassays were performed in a drop system, monitoring the frequency decrease of the quartz-crystal microbalance device because of mass increasing during immunoreaction.

Protein Corona Engineering of Lipid Nanoparticles Enables Efficient Functional Gene Silencing in the Liver

Small, EarlyView.
By shaping the protein corona, lipid composition directs LNP tropism and enables the preferential delivery of a TIMP1‐targeting siRNA to liver macrophages. In a murine model of primary biliary cholangitis, this strategy promoted macrophage reprogramming and attenuated liver fibrosis.

Metal‐Organic Framework‐Templated Deconstruction‐Reconstruction Enables One‐Dimensional to Two‐Dimensional Self‐Assembly of Transition Metal Phosphates for High‐Performance Ammonia Sensing

Small, EarlyView.
One‐dimensional nickel phosphate nanofibres are transformed into two‐dimensional quasi‐nanosheets through a metal‐organic framework‐templated deconstruction‐reconstruction strategy. The hierarchical nanofibre‐assembled architecture provides rich mesoporosity, accessible adsorption sites, and rapid ammonia diffusion, enabling high‐performance QCM ...

Design of Cell Construction for Immunosensor Based Quartz Crystal Microbalance (QCM)

Natural B, 2012
The biosensor is a sensor device that combines biological compounds with a transducer. One type of biosensor that uses mass change detection techniques are QCM (Quartz Crystal Microbalance). QCM is a sensor that works with the principle of quartz crystal frequency shift due to mass deposition on the surface of the crystal. QCM can be used to detect the

Direct and quantitative detection of bacteriophage by "hearing" surface detachment using a quartz crystal microbalance

, 2001
We show that it is possible to detect specifically adsorbed bacteriophage directly by breaking the interactions between proteins displayed on the phage coat and ligands immobilized on the surface of a quartz crystal microbalance (QCM).

Investigation of Tin Oxide Atomic Layer Deposition on the Performance of Evaporated Perovskite Solar Cells

Small, EarlyView.
Impact of co‐reactants and their doses utilized during the atomic layer deposition of SnOx on perovskite/C60 structures on the performance of p‐i‐n perovskite solar cells. ABSTRACT Although tin oxide (SnOx) layers grown using atomic layer deposition (ALD) are routinely employed in p‐i‐n perovskite solar cells (PSCs), the correlation between ALD process
