To take advantages, such as multiplex capacity, non-photobleaching property, and high sensitivity, of surface-enhanced Raman scattering (SERS)-based in vivo imaging, development highly enhanced SERS nanoprobes near-infrared (NIR) region is needed. A well-controlled morphology biocompatibility are essential features NIR nanoprobes. Gold (Au)-assembled nanostructures with controllable nanogaps signals within multiple hotspots could be a breakthrough.
The effective approach for coloration and chromatic sensing of electrospun cellulose fabrics with a natural colorant, curcumin, is demonstrated. To achieve high surface area, the morphology fiber was controlled to have rough porous through an electrospinning acetate (CA) solution under optimized parameters solvent system. resulting CA fibers were treated curcumin dye/NaOH ethanol solution, in which deacetylation high-quality simultaneously achieved. As control, cotton similar diameter smooth...
The development of three-dimensional polymeric systems capable mimicking the extracellular matrix is critical for advancing tissue engineering. To achieve these objectives, fibrous scaffolds with "clay"-like properties were successfully developed by coaxially electrospinning polystyrene (PS) and poly(ε-caprolactone) (PCL) selective leaching. As PS known to be nonbiodegradable vulnerable mechanical stress, layers present at outer surface removed using a "selective leaching" process. PCL that...
Electrostatic interactions contribute critically to the kinetic pathways and thermodynamic outcomes of peptide self-assembly involving one or more than charged amino acids. While it is well understood in protein folding that those acids with acidic/basic side chains could shift their pKas when placed a hydrophobic microenvironment, what extent aggregation monomeric units from bulk solution alter status how this change pKa values would reciprocally impact assembly outcomes. Here, we design...
A bioinspired adhesive material, polydopamine (pDA), was employed as an interfacial glue to stably immobilize human neural stem cells (hNSCs) on the external surface of biodegradable polycaprolactone (PCL) microspheres, thereby serving versatile key systems that can be used for cell carriers. The pDA decoration PCL microspheres has been resulted in robust hNSC immobilization well proliferation their curved surfaces. coating transformed hydrophobic toward water‐friendly and sticky...

본 연구에서는 암모니아 기체 센싱이 가능한 polyacrylonitrile 기반 나노섬유를 제작하기 위한 bromocresol green 염료의 나노섬유 담지 방법에 대하여 고찰하였다. 표면에 염료를 직접 도포하는 방법(도포법)과 고분자 용액 제조 시 혼합하여 용액을 제조하는 방법(혼합법)을 적용하여 제작하였고, 각각의 제조법으로 제작한 나노섬유가 기체에 노출되었을 때 나타나는 색채 변화 거동을 관찰하였다. 도포법의 경우 노출 수 초 가량의 응답 시간의 즉각적인 반응을 보여주었고, 함께 도포된 시트르산의 함량에 따라 초기 속도와 가역성에 차이가 발생하였다. 그러나 혼합법의 도포법에서 구현되지 못한 완벽한 가역성을 보여주었다. 연구가 제시하는 비색 센서 제작에 따른 거동 특성을 통해 추후 개발되는 염료 대한 방향성을 제시할 있을 것이다.
Abstract Backgroud: Surface-enhanced Raman scattering (SERS) imaging is widely exploited, given its advantages such as multiplex capacity, non-photobleaching property, and high sensitivity. Near-infrared (NIR) radiation suitable for in vivo studies because it exhibits good tissue penetration capability.
