Strategic positioning and accelerating regulatory clearance for new ventures

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary How do new ventures strategically position their products to accelerate regulatory clearance? We investigate this question in the medical device industry, where regulatory clearance is a prerequisite for market entry. We examine 239 new firms' 510(k) device clearances by the FDA between 2001 and 2019.

High Sensitivity Cardiac Troponin I Detection via MP‐Locked Aptamer and Multimeric DNAzyme‐Coupled Hyperbranched Hybridization Chain Reaction

open access: yesSmall, EarlyView.
We report a magnetic particle anchored locked aptamer platform integrated with hyperbranched HCR and DNAzyme amplification for enzyme‐free, ultrasensitive detection of cardiac troponin I. The assay achieves a 0.25 ng/L detection limit within 25 minutes and enables cross‐species MI detection, with machine learning classification reaching 90% accuracy ...

Flattening Energy Puddles for Enhanced Charge Transport in Wrinkled WSe2

open access: yesSmall, EarlyView.
Strain‐inducing wrinkles in 1L‐WSe2 create carrier‐trapping energy puddles. Trioctylphosphine selenide (TOPSe) selectively passivates Se vacancies at these wrinkle sites, while steric hindrance suppresses basal‐plane reaction. Comprehensive suite of space‐resolved spectroscopic techniques reveals reduced nonradiative recombination, longer exciton ...

Guiding the Formation of Surface‐Confined 2D Metal–Organic Coordination Networks by Variation of Constituent Landing Energy in Electrospray Deposition of an Iron(II) Grid Complex

open access: yesSmall Methods, EarlyView.
Electrospray ion beam deposition (ES‐IBD) of an Fe(II) [2 × 2] grid complex onto Ag(111) reveals landing energy‐dependent fragmentation and self‐assembly. At higher landing energies, novel coordination networks emerge. This study highlights the unique potential of ES‐IBD in creating diverse metal–organic architectures on surfaces.
