Abstract
Photocages enable scientists to take full control over the activity of molecules using light as a biocompatible stimulus. Their emerging applications in photoactivated therapies call for efficient uncaging in the near-infrared (NIR) window, which represents a fundamental challenge. Here, we report synthetically accessible cyanine photocages that liberate alcohol, phenol, amine, and thiol payloads upon irradiation with NIR light up to 820 nm in aqueous media. The photocages display a unique chameleon-like behavior and operate via two distinct uncaging mechanisms: photooxidation and heterolytic bond cleavage. The latter process constitutes the first example of a direct bond scission by a single photon ever observed in cyanine dyes or at wavelengths exceeding 800 nm. Modulation of the beating rates of human cardiomyocytes that we achieved by light-actuated release of adrenergic agonist etilefrine at submicromolar concentrations and low NIR light doses (∼12 J cm-2) highlights the potential of these photocages in biology and medicine.

Abstract
Molecular diffusion and leakage impede the long-term retention of probes/drugs and may cause potential adverse effects in theranostic fields. Spatiotemporally manipulating the organelle-immobilization behavior of probes/drugs for prolonged tumor retention is indispensable to achieving effective cancer diagnosis and therapy. Herein, we propose a rational strategy that could realize near-infrared light-activated ribonucleic acids (RNAs) cross-linking for prolonged tumor retention and simultaneously endogenous hydrogen sulfide (H2S) monitoring in colorectal tumors. Profiting from efficient singlet oxygen (1O2) generation from Cy796 under 808 nm light irradiation, the 1O2-animated furan moiety in Cy796 could covalently cross-link with cytoplasmic RNAs via a cycloaddition reaction and realize organelle immobilization. Subsequently, specific thiolysis of Cy796 assisted with H2S resulted in homologous product Cy644 with reduced 1O2 generation yields and enhanced absolute fluorescence quantum yields (from 7.42 to 27.70%) with blue-shifted absorption and emission, which avoided the molecular oxidation fluorescence quenching effect mediated by 1O2 and validated fluorescence imaging. Furthermore, studies have demonstrated that our proposed strategy possessed adequate capacity for fluorescence imaging and endogenous H2S detection in HCT116 cells, particularly accumulated at the tumor sites, and retained long-term imaging with excellent biocompatibility. The turn-on fluorescence mode and turn-off 1O2 generation efficiency in our strategy successfully realized a diminished fluorescence cross-talk and oxidation quenching effect. It is adequately envisioned that our proposed strategy for monitoring biomarkers and prolonged tumor retention will contribute tremendous dedication in the clinical, diagnostic, and therapeutic fields.

Abstract
The favorable properties of cyanines (e.g., near-infrared (NIR) absorbance and emission) have made this class of dyes popular for a wide variety of biomedical applications. However, many cyanines are prone to rapid photobleaching when irradiated with light. In this study, we have exploited this undesirable trait to develop NIR-nanogels for NIR light-mediated cargo delivery. NIR-nanogels feature a photolabile cyanine cross-linker (Cy780-Acryl) that can cleave via dioxetane chemistry when irradiated. This photochemical process results in the formation of two carbonyl fragments and concomitant NIR-nanogel degradation to facilitate cargo release. In contrast to studies where cyanines are utilized as photocages, our approach does not require direct chemical attachment to the cargo, thus expanding our ability to deliver molecules that cannot be covalently modified. We showcase this feature by encapsulating a palette of small-molecule chemotherapeutics that feature a structurally diverse chemical architecture. To demonstrate site-selective release in vivo, we generated a murine model of breast cancer. Relative to nonlight irradiated and drug-free controls, treatment with NIR-nanogels loaded with paclitaxel (a potent cytotoxic agent) and NIR light resulted in significant attenuation of tumor growth. Moreover, we show via histological staining of the vital organs that minimal off-target effects are observed.

Abstract
Near‐infrared light (NIR; 650–900 nm) offers unparalleled advantages as a biocompatible stimulus. The development of photocages that operate in this region represents a fundamental challenge due to the low energy of the excitation light. Herein, we repurpose cyanine dyes into photocages that are available on a multigram scale in three steps and efficiently release carboxylic acids in aqueous media upon irradiation with NIR light up to 820 nm. The photouncaging process is examined using several techniques, providing evidence that it proceeds via photooxidative pathway. We demonstrate the practical utility in live HeLa cells by delivery and release of the carboxylic acid cargo, that was otherwise not uptaken by cells in its free form. In combination with modularity of the cyanine scaffold, the realization of these accessible photocages will fully unleash the potential of the emerging field of NIR‐photoactivation and facilitate its widespread adoption outside the photochemistry community.

Abstract
BACKGROUND Lipopolysaccharides (LPS) are considered the main molecular component in the outer membrane of gram-negative bacteria. The LPS molecule in the bacterial cell wall acts as a primary physical barrier and protects gram-negative bacteria from the surrounding environment. LPS (endotoxins) show immunomodulatory therapeutic properties as well as toxicity to the host cell, whereas potential applications encompass. OBJECTIVE This review article aims to describe the recent developments of lipopolysaccharides in nanocarrier systems for various applications such as vaccination, cancer chemotherapy and immune stimulants action. Different nanocarriers like cubosomes, niosomes, dendrimers and metal nanoparticles used in the delivery of actives are employed to decorate lipopolysaccharide molecules superficially. METHODS A narrative review of all the relevant papers known to the author was conducted. CONCLUSION Commercially available lipid nanoparticles contribute to many advances as promising nanocarriers in cancer therapy and are used as a vaccine adjuvant by improving the immune response due to their properties such as size, shape, biocompatibility, and biodegradability. Whereas lipopolysaccharide-decorated nanoparticles change the host's tolerability and increase the effectiveness of molecule in cancer immunotherapy. These nanoconjugate systems enhance overall immunogenic response and effectiveness in vaccine immunotherapy and targeted therapy, not only limited to humans application but also for poultry and aquaculture. Newer opportunities using lipopolysaccharides for the treatment and management of diseases with unique characteristics like the presence of lipoprotein that act as an alternative for bacterial infections over conventional dosage forms.

Abstract
Photoirradiation provides a convenient and biocompatible approach for spatiotemporal modulation of biological systems with photoresponsive components. The construction of molecular platforms with a photoresponse to be integrated into biomolecules for photomodulation has been of great research interest in optochemical biology. In this review, we summarize typical molecular platforms that are integratable with biomolecules for photomodulation purposes. We categorize these molecular platforms according to their excitation light source, namely ultraviolet (UV), visible (Vis) or near-infrared (NIR) light. The protype chemistry of these molecular platforms is introduced along with an overview of their most recent applications for spatiotemporal regulation of biomolecular function in living cells or mice models. Challenges and the outlook are also presented. We hope this review paper will contribute to further progress in the development of molecular platforms and their biomedical use.

Abstract
Traditional strategies of bone repair include autografts, allografts and surgical reconstructions, but they may bring about potential hazard of donor site morbidity, rejection, risk of disease transmission and repetitive surgery. Bone tissue engineering (BTE) is a multidisciplinary field that offers promising substitutes in biopharmaceutical applications, and chitosan (CS)-based bone reconstructions can be a potential candidate in regenerative tissue fields owing to its low immunogenicity, biodegradability, bioresorbable features, low-cost and economic nature. Formulations of CS-based injectable hydrogels with thermo/pH-response are advantageous in terms of their high-water imbibing capability, minimal invasiveness, porous networks, and ability to mold perfectly into an irregular defect. Additionally, CS combined with other naturally-derived or synthetic polymers and bioactive agents has proven to be an effective alternative to autologous bone and dental grafts. In this review, we will highlight the current progress in the development of preparation methods, physicochemical properties and applications of CS-based injectable hydrogels and their perspectives in bone and dental regeneration. We believe this review is intended as starting point and inspiration for future research effort to develop the next generation of tissue-engineering scaffold materials.
