Abstract
AbstractPolymers, especially charged polymers, are the key to a sustainable future, as they have the capability to act as alternatives to plastics, reduce the impact of global warming, and offer solutions to global environmental pollution problems. Biomaterial polymers have proven to be incredibly effective in a multitude of applications, including clinical applications. In the fields of cryobiology and cryopreservation, polymers have emerged as credible alternatives to small molecules and other compounds, yielding excellent results. This review outlines the results of research in the areas of polymer chemistry and cryobiology, which have not been discussed together previously. Herein, we explain how recent polymer research has enabled the development of polymeric cryoprotectants with novel mechanisms and the development of novel methods for the intracellular delivery of substances, such as drugs, using a cryobiological technique called the freeze-concentration effect. Our findings indicate that interdisciplinary collaboration between cryobiologists and polymer chemists has led to exciting developments that will further cell biology and medical research.

Abstract
Quantum dots (QDs) can be delivered efficiently inside macrophages using a freeze-concentration approach. In this study, we introduced a new, facile, high concentration-based freezing technology of low toxicity. We also developed QD-conjugated new hydrophobic polyampholytes using poly-l-lysine (PLL), a naturally derived polymer, which showed sustained biocompatibility, stability over one week, and enhanced intracellular delivery. When freeze-concentration was applied, the QD-encapsulated hydrophobic polyampholytes showed a higher tendency to adsorb onto the cell membrane than the non-frozen molecules. Interestingly, we observed that the efficacy of adsorption of QDs on RAW 264.7 macrophages was higher than that on fibroblasts. Furthermore, the intracellular delivery of QDs using hydrophobic polyampholytes was higher than those of PLL and QDs. In vitro studies revealed the efficient endosomal escape of QDs in the presence of hydrophobic polyampholytes and freeze-concentration. Collectively, these observations indicated that the promising combination of freeze-concentration and hydrophobic polyampholytes may act as an effective and versatile strategy for the intracellular delivery of QDs, which can be used for biological diagnosis and therapeutic applications.

Abstract
Cancer immunotherapy is a promising cancer terminator by directing the patient's own immune system in the fight against this challenging disorder. Despite the monumental therapeutic potential of several immunotherapy strategies in clinical applications, the efficacious responses of a wide range of immunotherapeutic agents are limited in virtue of their inadequate accumulation in the tumor tissue and fatal side effects. In the last decades, increasing evidences disclose that nanotechnology acts as an appealing solution to address these technical barriers via conferring rational physicochemical properties to nanomaterials. In this Review, an imperative emphasis will be drawn from the current understanding of the effect of a nanosystem's structure characteristics (e.g., size, shape, surface charge, elasticity) and its chemical modification on its transport and biodistribution behavior. Subsequently, rapid-moving advances of nanoparticle-based cancer immunotherapies are summarized from traditional vaccine strategies to recent novel approaches, including delivery of immunotherapeutics (such as whole cancer cell vaccines, immune checkpoint blockade, and immunogenic cell death) and engineered immune cells, to regulate tumor microenvironment and activate cellular immunity. The future prospects may involve in the rational combination of a few immunotherapies for more efficient cancer inhibition and elimination.

Abstract
Nanomedicine relies on the effective internalization of nanoparticles combined with polymeric nanocarriers into living cells. Thus, exploration of internalization is essential for improving the efficacy of nanoparticle-based strategies in clinical practice. Here, we investigated the physicochemical internalization of gold nanoparticles (AuNPs) conjugated with hydrophobic polyampholytes into cell-sized liposomes at a low but nonfrozen temperature. The hydrophobic polyampholytes localized in the disordered phase of the membrane, and internalization of AuNPs was enhanced in the presence of hydrophobic polyampholytes together with incubation at -3 °C as compared to 25 °C. These results contribute toward a mechanistic understanding for developing a model nanomaterials-driven delivery system based on hydrophobic polyampholytes and low temperature.

Abstract
Despite advances in nanoparticle delivery, established physical approaches, such as electroporation and sonication, result in cell damage, limiting their practical applications. In this study, we proposed a unique freeze concentration-based technique and evaluated the efficacy of the method using two types of nanoparticles: citrate-capped gold nanoparticles and carboxylated polystyrene nanoparticles. We further compared the internalisation behaviour of particles of various sizes with and without freezing. Confocal microscopic images showed that the uptake efficacy of 50 nm nanomaterials was greater than that of 100 nm particles. Polystyrene nanoparticles of 50 nm size had more favourable adsorption and internalisation behaviours compared to those of gold nanoparticles after freeze concentration. We also examined the possible endocytic pathways involved in the uptake of gold and polystyrene nanoparticles, and found that the route differed between non-frozen and frozen conditions. Overall, we determined the influence of the freeze concentration strategy on both nanomaterial internalisation and the endocytic uptake pathway. Our findings provide a mechanistic understanding of the internalisation of nanoparticles using a freezing approach and thereby contribute to further developments in nanotherapeutic applications.

Abstract
The transportation of biomolecules into cells is of great importance in tissue engineering and as stimulation for antitumor immune cells. Previous freezing strategies at ultracold temperatures (-80 °C) used for intracellular transportation exhibit certain limitations such as extended time requirements and harsh delivery system conditions. Thus, the need remains to develop simplified methods for safe nanomaterial delivery. Here, we demonstrated a unique strategy based on the ice-crystallization-induced freeze concentration for protein intracellular delivery in combination with a polyampholyte cryoprotectant. We found that upon sustained lowering of the temperature from -6 to -20 °C over a short duration, the adsorption of proteins onto the peripheral cell membrane was markedly increased through the facile ice-crystallization-induced freeze concentration. Furthermore, we proposed a freeze concentration factor (α) that depends on the freezing-point depression and is estimated from an analysis of the fraction of frozen water. Notably, the α values of the polyampholyte cryoprotectant were 8-fold higher than those of the currently used cryoprotectant dimethyl sulfoxide (DMSO) at particular temperatures of interest. Our results illustrate that the presence of a polyampholyte cryoprotectant significantly enhanced the adsorption of the protein/nanocarrier complex onto membranes compared to that obtained with DMSO because of the high freeze concentration. The present study demonstrated the direct relationship between freezing and the penetration of proteins across the periphery of the cell membrane by means of increased concentration during freezing. These results may be useful in providing a guideline for the intracellular delivery of biomacromolecules using ice-crystallization-induced continuous freezing combined with polyampholyte cryoprotectants.

Abstract
Aim: The purpose of present approach is to target C-Type lectin (CTL) receptors for preferential uptake by the macrophages/dendritic cells and improving the cross-presentation of ovalbumin. Materials & methods: Conventional and engineered nanoliposomes (MPNLs) were fabricated and extensively characterized. The nanoliposome(s) was spherical in shape; and their ζ potential, size and ovalbumin loading efficiency were recorded to be 268 ± 4.15 nm, 23.4 ± 0.35 mV, 46.65 ± 1.84%, respectively. Results: The findings demonstrate that MPNLs significantly improved the antigen uptake and its cross-presentation to evoke Th CD8+ cell-mediated cellular immunity. Conclusion: In a nutshell, this engineered approach mannose surface modification for active targeting to dendritic cells/macrophages and pH-dependent quick endosomal antigen release is a promising system for efficient cancer immunotherapy.
