Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

The Detectability of High Redshift Lyman Alpha Emission Lines Prior to the Reionization of the Universe

open access: yes, 2002
For a source of Ly alpha radiation embedded in a neutral intergalactic medium (IGM) prior to the reionization epoch, the emission line is strongly suppressed by the intervening IGM. The damping wing of the so-called Gunn-Peterson trough can extend to the

The Physical State of the Intergalactic Medium or Can We Measure Y? [PDF]

open access: yes, 1995
We present an argument for a {\it lower limit} to the Compton-$y$ parameter describing spectral distortions of the cosmic microwave background (CMB). The absence of a detectable Gunn-Peterson signal in the spectra of high redshift quasars demands a high ...

3D Bioprinted Human Synovium‐Cartilage Models Mimic Rheumatoid Arthritis Microenvironment and Recapitulate In Vivo Therapeutic Responses

open access: yesAdvanced Materials, EarlyView.
This study presents human in vitro rheumatoid arthritis models using chondrocytes recellularized type II collagen scaffold and 3D‐bioprinted Gelatin‐Matrigel hydrogels with fibroblast‐like synoviocytes, pro‐inflammatory macrophages, and protective barrier macrophages, closely recapitulating key rheumatoid arthritis pathological features.

Mesenchymal Stem Cell‐Inspired Microneedle Platform for NIR‐responsive Immunomodulation and Accelerated Chronic Wound Healing

open access: yesAdvanced Materials, EarlyView.
The research demonstrates a Mesenchymal Stem Cell‐inspired microneedle platform (MSCi@MN) that addresses chronic diabetic wounds by combining MSC‐derived extracellular nanovesicles (NV)–DNA conjugates in microneedle tips with photothermal MXene in the patch layer.

High Precision Analyses of Lyman alpha Damping Wing of Gamma-Ray Bursts in the Reionization Era: On the Controversial Results from GRB 130606A at z = 5.91

open access: yes, 2015
The unprecedentedly bright afterglow of Swift GRB 130606A at z = 5.91 gave us a unique opportunity to probe the reionization era by high precision analyses of the redward damping wing of Ly alpha absorption, but the reported constraints on the neutral ...

AGN Feedback Causes Downsizing [PDF]

open access: yes, 2005
We study the impact of outflows driven by active galactic nuclei (AGN) on galaxy formation. Outflows move into the surrounding intergalactic medium (IGM) and heat it sufficiently to prevent it from condensing onto galaxies.
