Mass‐Produced and High‐Performance Nanowell Biosensor Fabricated via Semiconductor Manufacturing for Rapid and Accurate COVID‐19 Diagnosis in the Clinical Field

open access: yesAdvanced Science, EarlyView.
A semiconductor‐fabricated nanowell biosensor enables rapid, scalable, and highly reproducible detection of SARS‐CoV‐2 antigens from nasal swabs within ∼10 minutes. Clinical validation in 249 retrospective and 243 prospective patient samples demonstrates high sensitivity and specificity, minimal cross‐reactivity, and robust batch‐to‐batch ...

Multimodal Wearable Biosensing Meets Multidomain AI: A Pathway to Decentralized Healthcare

open access: yesAdvanced Science, EarlyView.
Multimodal biosensing meets multidomain AI. Wearable biosensors capture complementary biochemical and physiological signals, while cross‐device, population‐aware learning aligns noisy, heterogeneous streams. This Review distills key sensing modalities, fusion and calibration strategies, and privacy‐preserving deployment pathways that transform ...

Central Africa

open access: yes
The pattern of infectious diseases in Central Africa is determined by climatic conditions and socioeconomic factors. The climate in most parts is tropical, i.e., hot and humid. The region is dominated by the Congo River and its tributaries, and the area is covered mostly by savannah or primary and secondary tropical rainforests.

Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

open access: yesAdvanced Science, EarlyView.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Ethical Precision in Nanoscale Brain Interfacing

open access: yesAdvanced Science, EarlyView.
As brain interfaces approach the nanoscale, precision no longer only measures—it knows, predicts, and potentially reshapes the mind. This work argues that traditional ethics fails under such conditions and proposes a shift toward continuous, operation‐based governance using the recovery–discovery framework to track, constrain, and responsibly steer ...

Correction of Geometrical Build-up Rate Formula of Double Tilt PDM

open access: yesShiyou jixie, 2016
Accurately designed build-up rate of PDM is the key technology to realize the sliding drilling. The additional build-up rate generated by the clearance effect was defined considering the influence of the clearance between the lower stabilizer and the ...

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

open access: yesAdvanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Peptide Receptor‐Functionalized AuNP‐Embedded Zwitterionic Biopolymeric Nanohydrogel for Electrochemical Sclerostin Sensing

open access: yesAdvanced Science, EarlyView.
We report an electrochemical biosensor that employs biopanning‐derived affinity peptides as selective receptors on a multifunctional chitosan–zwitterionic–gold nanoparticle (CS–ZI–AuNPs) nanohydrogel interface. The CS–ZI–AuNPs nanohydrogel exhibits antifouling properties, abundant sites for stable peptide immobilization, and efficient electrochemical ...
