Abstract
Poly(lactide-co-glycolide) (PLGA) is a biocompatible and biodegradable copolymer that has gained high acceptance in biomedical applications. In the present study, PLGA (Mw = 13,900) was synthesized by ring-opening polymerization in the presence of a biocompatible zinc-proline initiator through a green route. Irinotecan (Ir) loaded with efficient PLGA core-lipid shell hybrid nanocarriers (lipomers, LPs) were formulated with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino (polyethylene glycol)-2000] (DSPE-PEG-2000), using soya lecithin, by a nanoprecipitation method, and the fabricated LPs were designated as P-DSPE-Ir and P-DSPE-PEG-Ir, respectively. The formulated LPs were further validated for their physicochemical properties and biological potential for colon cancer application. The potential delivery of a poorly water-soluble chemotherapeutic drug (Ir) was studied for the treatment of colon cancer. LPs were successfully prepared, providing controlled size (80-120 nm) and surface charge (∼ -35 mV), and the sustained release properties and cytotoxicity against CT-26 colon cancer cells were studied. The in vivo biodistribution and tumor site retention in CT-26 xenograft tumor-bearing Balb/C mice showed promising results for tumor uptake and retention for a prolonged time period. Unlike P-DSPE-Ir, the P-DSPE-PEG-Ir LP exhibited significant tumor growth delay as compared to untreated and blank formulation-treated groups in CT-26 (subcutaneous tumor model) after 4 treatments of 10 mg irinotecan/kg dose. The biocompatibility and safety of the LPs were confirmed by an acute toxicity study of the optimized formulation. Overall, this proof-of-concept study demonstrates that the PLGA-based LPs improve the efficacy and bioavailability and decrease neutropenia of Ir to combat colon cancer.

Abstract
The widespread use of video-assisted thoracoscopic surgery (VATS) has triggered the rapid expansion in the field of computed tomography (CT)-guided preoperative localization and near-infrared (NIR) fluorescence image-guided surgery. However, its broader application has been hindered by the absence of ideal imaging contrasts that are biocompatible, minimally invasive, highly resolvable, and perfectly localized within the diseased tissue. To achieve this goal, we synthesize a dextran-based fluorescent and iodinated hydrogel, which can be injected into the tissue and imaged with both CT and NIR fluorescence modalities. By finely tuning the physical parameters such as gelation time and composition of iodinated oil (X-ray contrast agent) and indocyanine green (ICG, NIR fluorescence dye), we optimize the hydrogel for prolonged localization at the injected site without losing the dual-imaging capability. We validate the effectiveness of the developed injectable dual-imaging platform by performing image-guided resection of pulmonary nodules on tumor-bearing rabbits, which are preoperatively localized with the hydrogel. The injectable dual-imaging marker, therefore, can emerge as a powerful tool for surgical guidance.

Abstract
A poly(d,l-lactide-co-glycolide) (PLGA) copolymer was synthesized using the ring-opening polymerization of d,l-lactide and glycolide monomers in the presence of zinc proline complex in bulk through the green route and was well characterized using attenuated total reflectance-Fourier transform infrared, 1H and 13C nuclear magnetic resonance, gel permeation chromatography, differential scanning calorimetry, X-ray diffraction, matrix-assisted laser desorption/ionization time-of-flight, etc. Furthermore, PLGA-conjugated biotin (PLGA-B) was synthesized using the synthesized PLGA and was employed to fabricate nanoparticles for irinotecan (Ir) delivery. These nanoparticles (PLGA-NP-Ir and PLGA-B-NP-Ir) were tested for physicochemical and biological characteristics. PLGA-B-NP-Ir exhibited a stronger cellular uptake and anticancer activity as compared to PLGA-NP-Ir in CT-26 cancer cells (log p < 0.05). The accumulation and retention of fluorescence-labeled nanoparticles were observed to be better in CT-26-inoculated solid tumors in Balb/c mice. The PLGA-B-NP-Ir-treated group inhibited tumor growth significantly more (log p < 0.001) than the untreated control, PLGA-NP-Ir, and Ir-treated groups. Furthermore, no body weight loss, hematological, and blood biochemical tests demonstrated the nanocarriers' nontoxic nature. This work presents the use of safe PLGA and the demonstration of a proof-of-concept of biotin surface attached PLGA nanoparticle-mediated active targeted Ir administration to combat colon cancer. To treat colon cancer, PLGA-B-NP-Ir performed better due to specific active tumor targeting and greater cellular uptake due to biotin.

Abstract
A multivalent ligand delivery system holds tremendous potential in the field of tumor-targeted drug delivery. It addresses the challenges posed by the low affinity between small molecule ligand receptors and the rapid metabolism of small molecule drug conjugates (SMDCs) in vivo. Notably, existing multivalent ligand systems have demonstrated significant anti-tumor activity in various tumor models. In this study, we have developed a novel multivalent ligand delivery system for SN38, utilizing acetazolamide, a carbonic anhydrase IX (CA IX) inhibitor, as the target ligand. Our multivalent ligand delivery systems exhibited superior metabolic stability and enhanced targeting specificity compared to SMDC molecules. Furthermore, they demonstrated improved anti-proliferation activity, addressing the existing challenges associated with the low receptor affinity and rapid metabolism of SMDCs.

Abstract
Now-a-days, the polysaccharides are extensively employed for the delivery of small-molecule drugs ascribed to their excellent biocompatibility, biodegradability and modifiability. An array of drug molecules is often chemically conjugated with different polysaccharides to augment their bio-performances. As compared to their therapeutic precursors, these conjugates could typically demonstrate an improved intrinsic solubility, stability, bioavailability and pharmacokinetic profiles of the drugs. In current years, various stimuli-responsive particularly pH and enzyme-sensitive linkers or pendants are also exploited to integrate the drug molecules into the polysaccharide backbone. The resulting conjugates could experience a rapid molecular conformational change upon exposure to the microenvironmental pH and enzyme changes of the diseased states, triggering the release of the bioactive cargos at the targeted sites and eventually minimize the systemic side effects. Herein, the recent advances in pH and enzyme -responsive polysaccharide-drug conjugates and their therapeutic benefits are systematically reviewed, following a brief description on the conjugation chemistry of the polysaccharides and drug molecules. The challenges and future perspectives of these conjugates are also precisely discussed.

Abstract
Abstract
Magnetic hyperthermia therapy (MHT) is a highly promising therapeutic modality for the treatment of different kinds of cancers and malignant tumors. The therapy is based on the concept that; iron oxide nanoparticles deposited at cancer sites can generate heat when exposed to an alternating current magnetic field or near infrared radiation and consequently destroying only the cancer cells by exploiting their vulnerability to heat. The fact that the treatment is at molecular level and that iron oxide nanoparticles provide more guided focus heating justifies its efficacy over treatment such as surgery, radiation therapy and chemotherapy. Nevertheless, the spread of MHT as the next-generation therapeutics has been shadowed by insufficient heating especially at the in vivo stage. This can be averted by modifying the iron oxide nanoparticle structure. To this end, various attempts have been made by developing a magnetic hybrid nanostructure capable of generating efficient heat. However, the synthesis method for each component (of the magnetic hybrid nanostructure) and the grafting process is now an issue. This has a direct effect on the performance of the magnetic hybrid nanostructure in MHT and other applications. The main objective of this review is to detail out the different materials, methods and characterization techniques that have been used so far in developing magnetic hybrid nanostructure. In view of this, we conducted a comprehensive review and present a road map for developing a magnetic hybrid nanostructure that is capable of generating optimum heat during MHT. We further summarize the various characterization techniques and necessary parameters to study in validating the efficiency of the magnetic hybrid nanostructure. Hopefully, this contribution will serve as a guide to researchers that are willing to evaluate the properties of their magnetic hybrid nanostructure.

Abstract
Magnetic ferrite nanoparticles (MNPs) coated with biocompatible polymers capable of drug loading and release are fascinating nanostructures for delivering anti-cancer drugs. Herein, we report the synthesis and characterization of a novel β-cyclodextrin-folate-tethered dextran polymer. Nickel-zinc ferrite nanoparticles are prepared and coated with the polymer to form a biocompatible hybrid magnetic nanocarrier. To establish the significance of folate unit of the polymer in anticancer activity, a similar derivatized polymer, i.e. β-cyclodextrin-dextran conjugate without folate tether is used for comparison. The size of the hybrid MNPs is ∼20 nm, which is a size suitable for cancer drug targeting. The polymer-coated magnetic nanocarriers are soft ferromagnets as suggested by their narrow magnetic hysteresis loops. The anticancer drug camptothecin (CPT) is loaded on the magnetic nanocarriers. The drug loading efficiency is observed to be above 92%. The nanocarriers show sustained in vitro drug release for above 45 h. The in vitro cytotoxicity studies reveal that the loaded CPT retains its potency in the nanocarrier and the folate-tethered nanocarrier shows better anticancer activity than the one which does not carry a folate unit. The magnetic nanocarrier is suitable for magnetic field-guided drug transport, enhanced drug loading and release and folate receptor-mediated endocytotic uptake of drugs by cancer cells.
