An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

open access: yesAdvanced Functional Materials, EarlyView.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.

A 55 V, 6.6 nV/√Hz Chopper Operational Amplifier with Dual Auto-Zero and Common-Mode Voltage Tracking

open access: yesEng
For high-voltage signal detection applications, an auto-zero and chopper operational amplifier (OPA) is proposed in this paper. With the auto-zero and chopper technique, the OPA adopts an eight-channel Ping-Pong mechanism to reduce the high-frequency ...

Infusible Extracellular Matrix Biomaterial Enhances Cell‐Specific Pro‐Repair Responses Following Acute Myocardial Infarction

open access: yesAdvanced Healthcare Materials, EarlyView.
We measure the cell‐specific responses of administering infusible ECM (iECM) in acute myocardial infarction (MI) across multiple timepoints. Using single‐nucleus RNA sequencing and spatial transcriptomics, we measure macrophage activation, fibroblast remodeling, increased vascular development, lymphangiogenesis, cardioprotection, and neurogenesis ...

Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

open access: yesAdvanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

Identity, community and embodiment: Chopper’s tattoo tour [PDF]

open access: yes, 2011
Heavy Metal fans have a unique style of dress, music and interaction via which a sub-cultural community is formed and maintained. This article explores how this community is embodied through tattoos and the display of cultural symbols associated with the

Photoresponsive Adaptive Reconfiguration of Single‐Atom Interface With Intermittent Light and Soft Ionic Lattices

open access: yesAdvanced Materials, EarlyView.
We present a photoresponsive platform that integrates SACs with halide perovskite supports, turning perovskite ion mobility, typically a stability concern, into a functional mechanism for light‐regulated self‐repair and reversible atomic reconfiguration. Adaptive metal‐support interactions are established through bandgap‐funnel engineering and the soft
