Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Determination and Progress in Establishing the Robotic Observatory of Space Objects (ROSO)

Machines
The gradual increase in man-made objects in the space surrounding our planet is becoming increasingly evident. This significant rise in terrestrial materials is reflected in a greater presence of artificial satellites, space debris and waste from space ...

‘Control Space?: Cinematic Representations of Surveillance Space between Discipline and Control’

, 2012
Recent developments in surveillance practices and their related technologies suggest that the heretofore dominant Foucauldian paradigm of discipline, with its sites of confinement in which space is “segmented, immobile [and] frozen”, may no longer be an ...

The Ambivalent Subject: Reconciling Contradictory Subjective Experiences of Surveillance

, 2020
This article discusses the surveillant assemblage operating within the brandscape of two American mega–casinos and the ways in which the mechanisms of this surveillance impact the subjective experiences of older adults who frequent these facilities in ...

Viral Infection‐Inspired Autonomous Detection of Fusion‐Competent Viruses for Screening and Environmental Surveillance

Advanced Materials, EarlyView.
Inspired by viral entry mechanisms, the FUSION assay enables autonomous detection of respiratory viruses via membrane fusion–triggered CRISPR‐Cas13a activation. VEACON selectively fuses with fusion‐competent viruses, triggering fluorescence within confined vesicles.

Lightweight Spatial–Frequency Constraint Propagation Framework for Satellite Detection in Space Surveillance

Aerospace
Satellite object detection in space surveillance is challenged by sparse and weak targets in large-scale, structured backgrounds (e.g., star fields, clouds, and streak noise). Such interference is not random but exhibits spatial correlation and frequency

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

Advanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

Advanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

Surface Tensions: Skate-Stoppers and the Surveillance Politics of Small Spaces

, 2022
Skate-stoppers are ubiquitous objects installed on outdoor surfaces in built environments all over the world. Skate-stoppers are an essential part of low-tech security of urban surfaces at a micro-scale—a single bench, handrail, or ledge—with the sole ...
