Immunotherapy, as a groundbreaking cancer treatment, has gained considerable attention for its utilization of the body’s immune system to combat tumors [1]. This therapy induces tumor cell apoptosis, triggering a sustained anti-tumor immune response and effectively preventing tumor recurrence and metastasis [2]. The fundamental principle lies in inducing tumor cell death through specific treatment modalities, leading to the release of a cascade of signaling molecules and antigens, thereby mobilizing the immune system to actively identify and attack tumor cells [3].

Mass spectrometry (MS) stands as a pivotal tool for chemical analysis in the textile industry, capable of scrutinizing the vast majority of reported harmful chemicals. With the ever-increasing number of banned chemicals in textiles, there is a pressing need for a more systematic compilation of relevant literature on MS utilization to identify and quantify harmful substances in textiles. This article comprehensively reviews the role of MS in textile analysis over the past two decades, encompassing a wide range of sample preparation techniques, such as energy-assisted extraction, solid-phase microextraction, liquid-phase microextraction, and QuEChERS. Furthermore, it delves into MS techniques, such as gas chromatography–MS, liquid chromatography–MS, inductively coupled plasma–MS, ion mobility spectrometry–MS, and ambient ionization MS. Moreover, it offers a brief glimpse into the future of MS development in this field, highlighting ongoing research into additional sample preparation techniques for detecting hazardous chemicals in textiles. Notably, it underscores the growing interest in ambient ionization MS and the coupling of chromatography with high-resolution MS.

The test methods of deodorization fabric are studied in daily life. In view of different deodorization fabrics and source gases,the detector tube method and gas chromatography-flame ionization detector ( GC-FID ) method were chosen to test the deodorizing rates of fabric and the influencing factors on deodorization test were discussed. Through the two methods,the residual concentration of odorous substance after adsorption can be measured,and the deodorizing rates of deodorization fabric can be got by calculation. The results show that the two test methods are both appropriate for deodorization test of fabric.

Hyperbranched polyamidoamines （HPAs） were directly employed as macroinitiators to initiate the Sn（Oct）2 catalyzed ring-opening polymerization of ε-caprolactone （CL）, resulting in multiarm star copolymers with poly（6- caprolactone）（PCL） as shells and HPA as core （HPA-b-PCL）. From 1H-NMR characterization it was deduced that both the primary amines and the secondary amide groups of HPAs could initiate the CL polymerization, and the initiation efficiency increased when more CL monomers were fed. The average arm-numbers of the obtained stars were in the range of 115-353. Differential scanning calorimetry measurements demonstrated that the melting and crystallization temperatures, fusion and crystallization enthalpy and the degree of crystallinity of the star polymers increased as the PCL arm length increased. HPA- b-PCL stars could be used as nanocarriers to efficiently accommodate anionic dyes at acidic condition, while load cationic dyes at basic condition. Compared with the dye-loading behavior of multiarrn star PCL with the neutral hyperbranched polyglycerol as core, it was deduced that HPA-b-PCL nanocarriers accommodated anionic dyes using the HPA core, while loaded cationic dyes using both the HPA core and the PCL shell. Dynamic light scattering analyses also supported such deduction. Furthermore, HPA-b-PCL nanocarriers could selectively load the anionic Eosin Y or the cationic methylene blue from their mixture at pH = 6 or 9, respectively, realizing their separation.

Primary aromatic amines （PAAs） are substances with toxicity and suspected human carcinogenicity. A facile method for highly sensitive detection of PAAs using surface-enhanced Raman spectroscopy （SERS） is reported. The immobilization of Au nanoparticles （AuNPs） on the glycidyl methacrylate-ethylene dimethacrylate （GMA-EDMA） materials makes the suhstrate a closely packed but not aggregated Au NP arrays which provides a prominent SERS enhancement. Four PAAs with different substituent groups, namely, p-toluidine, p-nitroaniline, benzidine and 4,4-methylene-bis-（2-chloroaniline） have been successfully identified and quantified. High sensitivity and good linear relationship between SERS signals and concentrations of PAAs are obtained for all four PAAs.

Phenylethanolamine A （PEA）, a fl-agonist, was found to be illegally used as a growth promoter in pigs last year, causing Chinese government＇s great attention. Here, a sensitive electrochemical method was developed for detecting PEA by immobilization of gold nanoparticles （AuNPs）, multiwalled carbon nanotubes （MWCNTs） and Nation on the surface of a glassy carbon electrode （GCE）. The Nafion/MWCNTs/AuNPs film was characterized by scanning electronic micrographs （SEM） and electrochemical impedance spectroscopy （EIS）. The electrochemical behaviors of PEA at the modified GCE were investigated in detail. The synergetic effects of AuNPs, MWCNTs and Nation amplify the electrochemical reduction signal of PEA, and result in high sensitivity for PEA determination. Under the optimal conditions, the electrochemical sensor shows a wide linear range of 0.01 to 10 μmol/L with a detection limit of 0.005μmol/L. Moreover, the fabricated sensor presents high selectivity and long-term stability, which paves a new way for simple, rapid, sensitive detection of PEA.
