Article Abstract
Development of soft and conductive micro devices represents a demanding research topic in various biomedical applications, particularly organic bioelectronics. Among various fabrication methods, two-photon polymerization (2PP) using a wide range of photocurable inks is a promising 3D printing technique for construction of structures in submicron resolution. Herein, we introduce a novel conductive photosensitive resin by using poly (3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) and poly(ethylene glycol) diacrylate), and fabricate 3D conductive polymeric microstructures via 2PP. In the developed resin, presence of PEDOT:PSS significantly enhances the electrical conductivity of microstructures (~ 10 orders of magnitude).Clinical Relevance- Conductive microdevices based on the PEDOT:PSS-doped resin open new avenues in a broad range of biomedical research areas including neural interfaces, biosensors, and bioelectronics.

The Werner syndrome RecQ helicase (WRN) has recently emerged as a novel synthetic lethality target for microsatellite instability-high (MSI-H) cancers. However, available WRN inhibitors or degraders is still lacking so far. Particularly, chemically designed probes capable of degrading WRN irrespective of microsatellite status remain unexplored.

Hydrogel-based bioinks are widely adopted in digital light processing (DLP) 3D printing. Modulating their mechanical properties is especially beneficial in biomedical applications, such as directing cell activity toward tissue regeneration and healing. However, in both monolithic and granular hydrogels, the tunability of mechanical properties is limited to parameters such as cross-linking or packing density.

Background: When analyzing cells in culture, assessing cell morphology (shape), confluency (density), and growth patterns are necessary for understanding cell health. These parameters are generally obtained by a skilled biologist inspecting light microscope images, but this can become very laborious for high-throughput applications. One way to speed up this process is by automating cell segmentation.

Understanding acute infectious disease dynamics at individual and population levels is critical for informing public health preparedness and response. Serological assays, which measure a range of biomarkers relating to humoral immunity, can provide a valuable window into immune responses generated by past infections and vaccinations. However, traditional methods for interpreting serological data, such as binary seropositivity and seroconversion thresholds, often rely on heuristics that fail to account for individual variability in antibody kinetics and timing of infection, potentially leading to biased estimates of infection rates and post-exposure immune responses.
