Abstract
Lipid nanoparticles (LNPs) are emerging as one of the most promising drug delivery systems. The long-circulating effect of intact LNPs (i-LNPs) is the key to efficacy and toxicity in vivo. However, the significant challenge is specific and sensitive detection of i-LNPs. Herein, a dual-recognition fluorescence enzyme-linked immunosorbent assay (DR-FELISA) was developed to directly isolate and detect i-LNPs by combining dual-recognition separation with a one-step signal amplification strategy. The microplates captured and enriched i-LNPs through antibody-antigen reaction. Dual-chol probes were spontaneously introduced into the lipid bilayer of captured i-LNPs, converting the detection of i-LNPs into the detection of double-cholesterol probes. Finally, the end of the dual-chol probes initiated the localized scaffolding autocatalytic DNA circuits (SADC) system for further signal amplification. The SADC system provides a sensitive and efficient amplifier through localized network structures and self-assembled triggers. Simultaneous recognition of i-LNPs surface PEG-lipid and lipid bilayer structures significantly eliminates interference from biological samples. i-LNPs were detected with high selectivity, ranging from 0.2 to 1.25 mg/mL with a limit of detection of 0.1 mg/mL. Moreover, this method allows the isolation and quantitative analysis of different formulations of i-LNPs in serum samples with a satisfactory recovery rate ranging from 94.8 to 116.3%. Thus, the DR-FELISA method provides an advanced platform for the exclusive and sensitive detection of i-LNPs, providing new insights for the study of the quality and intracorporal process of complex formulations.

Discrimination of polysorbate 20 by high-performance liquid chromatography-charged aerosol detection and characterization for components by expanding compound database and library. J Pharm Anal 2024; 14:100929. [PMID: 38799234 PMCID: PMC11126531 DOI: 10.1016/j.jpha.2023.12.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/27/2023] [Accepted: 12/28/2023] [Indexed: 05/29/2024] Open
Abstract
Analyzing polysorbate 20 (PS20) composition and the impact of each component on stability and safety is crucial due to formulation variations and individual tolerance. The similar structures and polarities of PS20 components make accurate separation, identification, and quantification challenging. In this work, a high-resolution quantitative method was developed using single-dimensional high-performance liquid chromatography (HPLC) with charged aerosol detection (CAD) to separate 18 key components with multiple esters. The separated components were characterized by ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS) with an identical gradient as the HPLC-CAD analysis. The polysorbate compound database and library were expanded over 7-time compared to the commercial database. The method investigated differences in PS20 samples from various origins and grades for different dosage forms to evaluate the composition-process relationship. UHPLC-Q-TOF-MS identified 1329 to 1511 compounds in 4 batches of PS20 from different sources. The method observed the impact of 4 degradation conditions on peak components, identifying stable components and their tendencies to change. HPLC-CAD and UHPLC-Q-TOF-MS results provided insights into fingerprint differences, distinguishing quasi products.

Abstract
Unraveling the cytotoxicity and cellular uptake of low, medium and high molecular weight polyethylene glycol (PEG) in cells is important for evaluation of therapeutic efficacy and toxicity of PEGylated drug delivery systems. In this study, cellular uptake of PEG600, PEG2K, PEG4K and PEG10K in MCF-7 cells was first studied by an UPLC-MS/MS assay coupled with collision induced dissociation (CID) in source technique. The CID of PEG in source with high values of declustering potentials generates numerous PEG-related product ions. These PEG-related fragment ions can be further broken into specific product ions in the collision cell as alternative ions for detection of PEG. The quantification of PEG was finally performed with the MRM transition (m/z 221.0 → 89.0). The experimental results indicated that the toxicity of PEG600, PEG2K, PEG4K and PEG10K was not significant at concentrations of 5-1200 μg/mL and the amounts of PEG polymers entry into MCF-7 cells at was small. The greenness of the developed analytical methods was also assessed by Analytical Eco-Scale, Analytical Greenness calculator (AGREE) and Green Analytical Procedure Index (GAPI) in this study.

Abstract
Polyethylene glycol (PEG) is one of the most commonly used polymers in drug delivery systems. The investigation of the pharmacokinetic behavior of PEG is important for revealing the toxicity and efficiency of PEG-related Nano-drug delivery systems. A high through-put and selective ultra-high-performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS) method coupled with collision-induced dissociation (CID) in source technique was developed and validated to determine PEG1K polymers in cellular samples in this study. The countless precursor ions of PEG1K are dissociated in the source to generate numerous product ions which have different numbers of subunits. The transition of [M+H]+ precursor ions → product ions at m/z 177.1 (four subunits)→89.1 (two subunits) was selected to determine PEG1K due to its high sensitivity. The UHPLC-MS/MS method coupled with CID in the source showed good linearity over the range of 0.1-10 μg/mL. Intra-day and inter-day accuracies and precisions of the assay were all within ± 12.39%. The assay was successfully applied to a cellular pharmacokinetic study of PEG1K in human breast cancer cells. The cytotoxicity of PEG1K polymers was also studied and the results indicated that the cytotoxicity of PEG1K was not significant in the range of 5-1200 μg/mL.

Abstract
The in-depth structural and compositional investigation of biodegradable polymeric materials, neat or partly degraded, is crucial for their successful applications. Obviously, an exhaustive structural analysis of all synthetic macromolecules is essential in polymer chemistry to confirm the accomplishment of a preparation procedure, identify degradation products originating from side reactions, and monitor chemical-physical properties. Advanced mass spectrometry (MS) techniques have been increasingly applied in biodegradable polymer studies with a relevant role in their further development, valuation, and extension of application fields. However, single-stage MS is not always sufficient to identify unambiguously the polymer structure. Thus, tandem mass spectrometry (MS/MS) has more recently been employed for detailed structure characterization and in degradation and drug release monitoring of polymeric samples, among which are biodegradable polymers. This review aims to run through the investigations carried out by the soft ionization technique matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and electrospray ionization mass spectrometry (ESI-MS) MS/MS in biodegradable polymers and present the resulting information.

Abstract
Polypropylene glycol (PPG) is a commonly used synthetic polymer in many fields. Investigating the toxicity and pharmacokinetic behavior of PPG polymers is necessary and important for evaluating their safety in medicine and daily cosmetics. In this study, PPG425, PPG1K and PPG2K were selected as the target polymers for cytotoxicity and cellular pharmacokinetics study of PPG polymers. Structural diversity and polydisperse molecular weights (MWs) are significant challenges for quantification of PPG polymers by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Collision induced dissociation in source or collision cell generated a series of PPG-related product ions at m/z 59.0, 117.1, 175.1, 233.2, 291.2, 349.3, 407.2, 465.3 and 523.5 corresponding to fragments containing 1, 2, 3, 4, 5, 6, 7, 8, 9 repeating propylene oxide subunits. PPG425 was determined by the sum of the MRM acquisitions used the transitions [M+H]+1 precursor ions → product ions. PPG1K and PPG2K were determined by the MRM acquisitions used the transitions [M+H]+1 precursor ions → product ions at m/z 233.2(four subunits)→59.0(one subunit). Based on the collision induced disassociation technique and structural specific product ions, pharmacokinetic studies of PEG425, PPG1K and PPG2K were successfully conducted in McF-7 cells. The experimental results revealed that PPG polymers are not biologically inert and they can enter into McF-7 cells. The safety of PPG polymers should be considered when they are used as pharmaceutical or cosmetic excipients.

Abstract
Poloxamers are commonly used pharmaceutical excipients. They are high molecular weight polymers formed from polypropylene oxide (PPO) and polyethylene oxide (PEO). However, PL124, a low molecular weight example in the poloxamer family, has rarely been reported, and there is no research into its tissue distribution in the body after administration. In this study, rat tissue samples were quantitatively studied via UHPLC-Q-TOF/MS after the intravenous administration of 10 mg kg-1 PL124. The quantitative method showed good sensitivity and selectivity. The linear range of PL124 was 0.1-5 μg mL-1 and the LLOQ was 0.1 μg mL-1. The relative error in terms of the accuracy was no higher than 13.9%, and the relative standard deviation in terms of the precision was no higher than 9.6%. The extraction recovery, matrix effect, and stability results of the established method were also satisfactory. The research showed that PL124 can be quickly distributed to large amounts of tissue, and tissue with higher levels of blood flow has higher concentrations. PL124 could be rapidly eliminated in 4 h from most organs, except the heart and liver. This study can be helpful for the further analysis of PL124.

Abstract
Poloxamer (PL)188 is a commonly used pharmaceutical excipient with unique physicochemical properties. In this study, an MSALL quantitative method for the determination of PL188 in rat plasma by UHPLC-Q-TOF/MS was developed and validated. PL188 was analyzed on PLRP-S reversed-phase column (50 × 4.6 mm, 8 μm, 1,000 Å) with mobile phase 0.1% formic acid-water and 0.1% formic acid in acetonitrile-isopropanol (2:3, v/v). The liner range was 0.1-10.0 μg/ml. A pharmacokinetic study was performed on rats at a dose of 5 mg/kg by intravenous injection. The pharmacokinetic parameters of intravenous injection were as follows: half-life was 2.0 ± 1.1 h, volume of distribution was 5.1 ± 3.2 L/kg, area under the concentration-time curve was 3.0 ± 0.6 μg/L h and clearance was 1.7 ± 0.3 L/h/kg. The results indicated that PL188 could be rapidly distributed to tissues with a high clearance rate. This study can provide a good reference for the further study of PL188.

Abstract
Poloxamer188 (PL188), as one of the most commonly used pharmaceutical excipients, has unique physicochemical properties and good biocompatibility, and so is playing an increasingly extensive role in the field of medicine. Currently, there are few studies on the tissue distribution of PL188 in vivo. In this study, the LC-MS method based on MSALL technique of quadrupole time of flight mass spectrometry for absolute quantitative analysis of poloxamer 188 in biological substrates was established for the first time. The tissue distribution of poloxamer188 in SD rats were studied using the established quantitative analysis method. To explore the distribution of PL188 in organs and tissues, PL188 was administered via rat tail vein at a dose of 5 mg/kg. Eight kinds of tissues including heart, liver, spleen, lung, kidney, stomach, muscle and brain of rats were collected at 0.25 h, 1 h and 4 h after administration. Tissue distributions showed the highest level was observed in kidney, then in stomach, which indicated PL188 mainly bioaccumulated in the kidney. This study can provide references for the further study of PL188.

Abstract
Poloxamer is a commonly used pharmaceutical excipient. It is a high molecular polymer formed using polypropylene oxide and polyethylene oxide units. Specifically, poloxamer 124 is one of the smaller molecular weight in the poloxamer series; however, its pharmacokinetic behaviors in vivo are still unclear. In this study, a method for quantifying poloxamer 124 in rat plasma through ultra-high-performance liquid chromatography coupled with quadrupole time of flight mass spectrometry was developed. The intravenous dosage of PL124 was 10 mg/kg. Plasma was collected at different times. The calibration curve was linear in the range of 0.1-5 μg/mL for the poloxamer 124 (r ≥ 0.9956) with the lower limit of quantitation of 0.1 μg/ml. The relative standard deviation of the intraday and interday precisions was below 8.0%, and the relative error of the accuracy was within ±12.0%. The extraction recovery, matrix effect, and stability were satisfactory in rat plasma. The validated method was successfully applied to a pharmacokinetic study of poloxamer 124 in rats. Results indicated that poloxamer 124 could be rapidly absorbed and eliminated through caudal vein injection. This study is helpful for the further study of poloxamer 124.

Meng X, Zhang Z, Tong J, Sun H, Fawcett JP, Gu J. The biological fate of the polymer nanocarrier material monomethoxy poly(ethylene glycol)- block-poly(d,l-lactic acid) in rat. Acta Pharm Sin B 2021; 11:1003-1009. [PMID: 33996412 PMCID: PMC8105770 DOI: 10.1016/j.apsb.2021.02.018] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Revised: 12/23/2020] [Accepted: 01/30/2021] [Indexed: 02/07/2023] Open
Abstract
Monomethoxy poly(ethylene glycol)-block-poly(d,l-lactic acid) (PEG-PLA) is a typical amphiphilic di-block copolymer widely used as a nanoparticle carrier (nanocarrier) in drug delivery. Understanding the in vivo fate of PEG-PLA is required to evaluate its overall safety and promote the development of PEG-PLA-based nanocarrier drug delivery systems. However, acquiring such understanding is limited by the lack of a suitable analytical method for the bioassay of PEG-PLA. In this study, the pharmacokinetics, biodistribution, metabolism and excretion of PEG-PLA were investigated in rat after intravenous administration. The results show that unchanged PEG-PLA is mainly distributed to spleen, liver, and kidney before being eliminated in urine over 48 h mainly (>80%) in the form of its PEG metabolite. Our study provides a clear and comprehensive picture of the in vivo fate of PEG-PLA which we anticipate will facilitate the scientific design and safety evaluation of PEG-PLA-based nanocarrier drug delivery systems and thereby enhance their clinical development.

Selective antitumor activity of drug-free TPGS nanomicelles with ROS-induced mitochondrial cell death. Int J Pharm 2020; 594:120184. [PMID: 33340597 DOI: 10.1016/j.ijpharm.2020.120184] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 11/29/2020] [Accepted: 12/13/2020] [Indexed: 12/15/2022]
Abstract
D-a-tocopheryl polyethylene glycol succinate (TPGS) as a FDA-approved safe adjuvant has shown an excellent application in the targeting delivery of antitumor drugs and overcoming multidrug resistance. Beside, TPGS can result in apoptogenic activity toward many tumor types because it can induce mitochondrial dysfunction. Therefore, TPGS can serve as an antineoplastic agent. However, the current research on the selective antitumor activity of TPGS is ignored. To reveal the issue, herein we develop a mitochondria-targeting drug-free TPGS nanomicelles with the hydrodynamic diameter of about 100 nm and outstanding serum stability by weak interaction-driven self-assembly of the amphiphilic TPGS polymer. Moreover, such drug-free TPGS nanomicelles intravenously injected into tumor-bearing mice exhibit long blood circulation time, superior tumor enrichment, and inhibit the tumor growth via inducing excessive reactive oxygen species (ROS) generation within tumor cells. Further in vitro and in vivo researches jointly demonstrate that drug-free TPGS nanomicelles have more significant antitumor effect on HeLa cells compared with that of other tumor cells. On the contrary, drug-free TPGS nanomicelles display the low toxicity toward normal cells and tissues. Taken together, these new findings confirm that TPGS drug-free nanomicelles represent simple, multifunctional, safe, and efficient antineoplastic agents, which can be expected to bring new light on the development of drug-free polymers for tumor therapy.

Impact of molecular weight on the mechanism of cellular uptake of polyethylene glycols (PEGs) with particular reference to P-glycoprotein. Acta Pharm Sin B 2020; 10:2002-2009. [PMID: 33163350 PMCID: PMC7606107 DOI: 10.1016/j.apsb.2020.02.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2019] [Revised: 01/15/2020] [Accepted: 02/01/2020] [Indexed: 12/27/2022] Open
Abstract
Polyethylene glycols (PEGs) in general use are polydisperse molecules with molecular weight (MW) distributed around an average value applied in their designation e.g., PEG 4000. Previous research has shown that PEGs can act as P-glycoprotein (P-gp) inhibitors with the potential to affect the absorption and efflux of concomitantly administered drugs. However, questions related to the mechanism of cellular uptake of PEGs and the exact role played by P-gp has not been addressed. In this study, we examined the mechanism of uptake of PEGs by MDCK-mock cells, in particular, the effect of MW and interaction with P-gp by MDCK-hMDR1 and A549 cells. The results show that: (a) the uptake of PEGs by MDCK-hMDR1 cells is enhanced by P-gp inhibitors; (b) PEGs stimulate P-gp ATPase activity but to a much lesser extent than verapamil; and (c) uptake of PEGs of low MW (<2000 Da) occurs by passive diffusion whereas uptake of PEGs of high MW (>5000 Da) occurs by a combination of passive diffusion and caveolae-mediated endocytosis. These findings suggest that PEGs can engage in P-gp-based drug interactions which we believe should be taken into account when using PEGs as excipients and in PEGylated drugs and drug delivery systems.

Abstract
The development of nano drug delivery systems (NDDSs) provides new approaches to fighting against diseases. The NDDSs are specially designed to serve as carriers for the delivery of active pharmaceutical ingredients (APIs) to their target sites, which would certainly extend the benefit of their unique physicochemical characteristics, such as prolonged circulation time, improved targeting and avoiding of drug-resistance. Despite the remarkable progress achieved over the last three decades, the understanding of the relationships between the in vivo pharmacokinetics of NDDSs and their safety profiles is insufficient. Analysis of NDDSs is far more complicated than the monitoring of small molecular drugs in terms of structure, composition and aggregation state, whereby almost all of the conventional techniques are inadequate for accurate profiling their pharmacokinetic behavior in vivo. Herein, the advanced bioanalysis for tracing the in vivo fate of NDDSs is summarized, including liquid chromatography tandem-mass spectrometry (LC-MS/MS), Förster resonance energy transfer (FRET), aggregation-caused quenching (ACQ) fluorophore, aggregation-induced emission (AIE) fluorophores, enzyme-linked immunosorbent assay (ELISA), magnetic resonance imaging (MRI), radiolabeling, fluorescence spectroscopy, laser ablation inductively coupled plasma MS (LA-ICP-MS), and size-exclusion chromatography (SEC). Based on these technologies, a comprehensive survey of monitoring the dynamic changes of NDDSs in structure, composition and existing form in system (i.e. carrier polymers, released and encapsulated drug) with recent progress is provided. We hope that this review will be helpful in appropriate application methodology for investigating the pharmacokinetics and evaluating the efficacy and safety profiles of NDDSs.

Abstract
Ultrahigh molecular weight (UHMW) poly(ethylene oxide) (PEO) is a synthetic hydrophilic polymer with wide dispersity which shows considerable promise as a hemostatic agent in the treatment of gastrointestinal bleeding. Currently there is no analytical method for the determination of highly disperse UHMW PEO in biological samples that would allow its characterization in vivo and support its clinical development. Although liquid chromatography-tandem mass spectrometry (LC-MS/MS) is a powerful bioanalytical tool, it faces major challenges when applied to UHMW PEO. In this work, we report a novel bioanalytical method for the determination of UHMW PEO involving microsolid phase extraction (μ-SPE), chromatography on a PLRP-S 1000 Å reversed phase column and detection by positive ion Q-Q-TOF MS using the MSALL technique. In this mode, dissociation of all precursor ions in Q2 generated a series of product ions at m/z 89.0715, 133.0854, 177.1047, and 221.1475 of which the product ion at m/z 133.0854 was common to all precursor ions and enabled quantitation of all polymers in UHMW PEO. The method was successfully applied to the determination of UHMW PEO polymers in rat plasma, urine, and feces after oral administration of 1700 kDa PEO. The results show that UHMW PEO is not absorbed into the blood and is largely eliminated unchanged in feces over 48 h. We maintain the method is sufficiently robust to be used in routine bioanalysis of polymers with UHMW and wide dispersity.

Abstract
Poly(ethylene glycol)-block-poly(lactic acid) (PEG-PLA) is a biocompatible and amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic PLA block, which can self-assemble into micelles in water. It is one of the most commonly used biodegradable polymers for drug encapsulation, drug solubilization and drug delivery. Due to the complexity and heterogeneity of PEG-PLA, the precise analysis of this polymer is a great challenge. This study reports an application of an UPLC tandem mass spectrometry coupled with in-source collision induced dissociation (CID) technique for the analysis of a model compound mPEG2000-PDLLA2500-COOH, which could be dissociated in source and generate a series of fragment ions corresponding to its subunits. These surrogate ions including PLA-specific and PEG-specific fragment ions could be further broken into specific product ions in collision cell. Finally, the ion transition at m/z 505.0 → 217.0 was selected for the quantitation of mPEG2000-PDLLA2500-COOH. This assay achieved a lower limit of quantitation (LLOQ) of 0.05 μg/mL with only 30 μL rat plasma. The linear range is 0.05 to 5 μg/mL. Intraday and interday accuracy and precision were within ±12.1%. The method was successfully applied to the pharmacokinetic study of mPEG2000-PDLLA2500-COOH in rats. The results revealed that LC-MS/MS coupled with in-source CID is a sensitive and specific strategy for analysis of PEG-PLA. This method can be potentially extended to the analysis of other pharmaceutical polymer excipients.

Abstract
Nanocarriers (NCs) are a type of drug delivery system commonly used to regulate the pharmacokinetic and pharmacodynamic properties of drugs. Although a wide variety of NCs has been developed, relatively few have been registered for clinical trials and even fewer are clinically approved. Overt or potential toxicity, indistinct mechanisms of drug release and unsatisfactory pharmacokinetic behavior all contribute to their high failure rate during preclinical and clinical testing. These negative characteristics are not only due to the NCs themselves but also to the materials of the drug nanocarrier system (MDNS) that are released in vivo. In this article, we review the main analytical techniques used for bioassay of NCs and MDNS and their pharmacokinetics after administration by various routes. We anticipate our review will serve to improve the understanding of MDNS pharmacokinetics and facilitate the development of NC drug delivery systems.

Abstract
As a result of their ability to transform into bulk cancer cells and their resistance to radiotherapy and chemotherapy, cancer stem cells (CSCs) are currently considered as a major obstacle for cancer treatment. Application of multiple drugs using nanocarriers is a promising approach to simultaneously eliminate noncancer stem cells (non-CSCs) and CSCs. Herein, to employ the advantages of nanomedicine while avoiding new excipients, pH-responsive prodrug (PEG-CH═N-DOX) was employed as the surfactant to fabricate cargo-free nanomedicine for codelivery of DOX conjugated prodrug with SN38 to synergistically eradicate breast cancer stem cells (bCSCs) and non-bCSCs. Through the intermolecular interaction between DOX and SN38, PEG-CH═N-DOX and SN38 were assembled together to form a stable nanomedicine. This nanomedicine not only dramatically enhanced drug accumulation efficiency at the tumor site but also effectively eliminated bCSCs and non-bCSCs, which resulted in achieving a superior in vivo tumor inhibition activity. Additionally, the biosafety of this nanomedicine was systematically studied through immunohistochemistry, blood biochemistry assay, blood routine examination, and metabolomics. The results revealed that this nanomedicine significantly reduced the adverse effects of DOX and SN38. Therefore, this simple yet efficient nanomedicine provided a promising strategy for future clinical applications.

Abstract
Fundamental studies on the cellular uptake and drug release of PEGylated nanomedicines are beneficial to understand their fate in vivo and construct ideal nanoparticle formulations. In this work, the detailed metabolic process of PEGylated doxorubicin (Dox) nanomedicines were investigated via confocal laser scanning microscopy (CLSM), flow cytometry (FCM), cytotoxicity test, fluorescence imaging in vivo (FLIV) and liquid chromatography tandem mass spectrometry (LC-MS/MS). Among them, only LC-MS/MS could accurately determine the content of PEGylated Dox and Dox in vitro and in vivo. To the best of our knowledge, this was the first time the PEGylated Dox and released Dox were simultaneously quantified. The interplay of molecular structures, cellular uptake, drug release, and antitumor effect was well characterized. PEG with high molecular weight impeded the cellular uptake of nanoparticles, and the acid-labile hydrazone bond between Dox and PEG promoted Dox release significantly. Cellular uptake and drug release play decisive roles in cytotoxicity and antitumor effect, as evidenced by LC-MS/MS. We emphasized that LC-MS/MS would be a practicable method to quantify PEGylated drugs without complex tags, which could be more in-depth to understand the interaction between PEGylated nanomedicines and their antitumor efficacy.
