The separation and detection of multi-component mixtures has always been a challenging task. Traditional detection methods often suffer from complex operation, high cost, and low sensitivity. Surface enhanced Raman scattering (SERS) technique is a high sensitivity, powerful and rapid detection tool, which can realize the specific detection of single substance components, but it must solve the problem that multi-component mixtures cannot be accurately determined. Thin layer chromatography (TLC) technology, as a high-throughput separation technology, uses chromatographic plate as the stationary phase, and could select different developing phases for separation experiments. The advantages of TLC technology in short distance and rapid separation are widely used in protein, dye and biomedical fields. However, TLC technology has limitations in detection ability and difficulty in obtaining ideal signal intensity. The combination of TLC technology and SERS technology made the operation procedure simple and the sample size small, which can achieve rapid on-site separation and quantitative detection of mixtures. Due to the rapid development of TLC-SERS technology, it has been widely used in the investigation of various complex systems. This paper reviews the application of TLC-SERS technology in food science, environmental pollution and biomedicine.

Objective: This economic evaluation compares two treatment strategies for patients with a diabetic foot ulcer (DFU): a lipido-colloid technology with nano-oligosaccharide factor (TLC-NOSF) dressing versus standard of care (SoC) over a one-year time horizon from the Vietnamese healthcare payer perspective.
Method: A Markov microsimulation model was developed to simulate weekly progression of DFUs over one year, comparing two treatment strategies. Using a willingness-to-pay threshold of VND 305.

Wound healing is an intricate physiological process, with acute and chronic wounds imposing significant burdens on the healthcare systems worldwide. This study reports the development fully biodegradable silica gel fiber (SGF) scaffolds for enhanced skin tissue regeneration. Three types of wound dressings, differing in their structure, are fabricated: pressure-spun silica gel µ-fibers (pSGF) allowing cell penetration, electrospun sub-µ silica gel fibers (eSGF) mimicking an extracellular matrix (ECM)-like sub-µ-structure with narrow mesh sizes allowing no cell ingrowth, and a hybrid scaffold combining both fiber types (peSGF) that combines the advantages of both structures.

Herbal formulations, widely used for their therapeutic properties, require rigorous analysis to ensure their safety, efficacy, and consistency. Flash chromatography and thin layer chromatography-mass spectrometry (TLC-MS) are powerful analytical tools that play a crucial role in the purification, identification, and quality control of herbal products. Flash chromatography enables rapid separation and purification of bioactive compounds from complex herbal mixtures, while thin layer chromatography provides a simple and effective method for compound fingerprinting.

CdTe QD-doped MIP-based TLC combined with a miniaturized fluorimeter system (namely the system) was developed to simultaneously detect malachite green (4-[(4-(dimethylamino)phenyl)(phenyl)methyl]-N,N-dimethylbenzenaminium chloride, MG) and crystal violet (4-(Bis{4-(dimethylamino)phenyl}methylidene)-N,N-dimethylcyclohexa-2,5-dien-1-iminium chloride, CV). The system integrated CdTe quantum dots-based molecularly imprinted polymers nanoparticles (CdTe-MIP/SiO NPs) with thin layer chromatography (TLC) plates. Firstly, CdTe-MIP/SiO NPs were synthesized by forming an imprinted layer on silica nanoparticle surfaces through a simple one-pot reaction.

The detection of aliphatic and aromatic biogenic amines (BAs) is important in food spoilage, environmental monitoring, and disease diagnosis and treatment. Existing fluorescent probes predominantly detect aliphatic BAs with single signal variation and low sensitivity, impairing the adaptability of discriminative sensing platforms. Herein, we present a visual chemosensor (galactose-functionalized pyrrolopyrrole -BODIPY, ) that simultaneously detects eight aliphatic and aromatic BAs in a real-time and intuitive way based on their unique electronic and structural features.
