Dimension-engineered synthesis of atomically thin II-VI nanoplatelets (NPLs) remains an open challenge. While CdSe NPLs have been made with confinement ranging from 2 to 11 monolayers (ML), CdTe NPLs have been significantly more challenging to synthesize and separate. Here we provide detailed mechanistic insight into the layer-by-layer growth kinetics of the CdTe NPLs.

Photodynamic therapy is a highly promising method for cancer adjuvant treatment. However, the current research on the microscopic changes during the photodynamic therapy process is still quite limited, which seriously impedes the deep understanding of the procedure. For this purpose, a novel polarity-responsive probe, , with excellent mitochondrial targeting and anchoring capabilities has been rationally designed and synthesized.

The application of physical fields is crucial for droplet generation and manipulation, underpinning technologies like printing, microfluidic biochips, drug delivery, and flexible sensors. Despite advancements, precise micro/nanoscale droplet generation and accurate microfluidic reactions remain challenging. Inspired by the liquid ejection mechanisms in microscopic organisms, an electrostatic manipulator for the precise capture, emission, and transport of microdroplets is proposed.

Multidrug-resistant (MDR) bacteria and their associated biofilms are major causative factors in eye infections, often resulting in blindness and presenting considerable global health challenges. Presently, mechano-bactericidal systems, which combine distinct topological geometries with mechanical forces to physically induce bacterial apoptosis, show promising potential. However, the physical interaction process between current mechano-bactericidal systems and bacteria is generally based on passive diffusion or Brownian motion and lacks the force required for biofilm penetration; thus, featuring low antibacterial efficacy.

Introduction: A positive surgical margin (R1 resection) is a relevant risk factor for local recurrence in patients with pancreatic ductal adenocarcinoma of the pancreas (PDAC). An intraoperative liquid biopsy (ILB) based on tumor cell mobilization could help to detect R1 resection intraoperatively.
Objective: To evaluate the potential role of the intraoperative circulating tumor cells (CTCs) and cluster mobilization on the R0/R1 detection.
