1. Polysaccharides

Polysaccharides are macromolecular carbohydrates composed of long chains of monosaccharide units linked by glycosidic bonds. They offer excellent biocompatibility, non-toxicity, and low immunogenicity, making them suitable for a wide range of biomedical applications.

2.Anticancer Reagents and APIs

NSP provides a broad selection of high-quality anticancer reagents and active pharmaceutical ingredients for drug development and related research.

3. Lipids

NSP functional lipids are used for the preparation of liposomes and nanoparticles. These liposomal or nanoparticle systems can be further modified through bioconjugation via functional groups on the lipid head, supporting a variety of delivery and formulation applications.

4. PEI-PEGs

NSP PEI-PEG polymers include PEG-grafted branched PEI and PEG-conjugated linear PEI. These materials are suitable for the delivery of oligonucleotides to cells and tissues in both in vitro and in vivo applications.

5. Poly(amino acid)s

Poly(amino acid)s can improve the solubility and stability of drug conjugates while supporting drug encapsulation and targeted delivery. They also offer advantages such as low toxicity, biodegradability, minimal immune stimulation, and the potential to help overcome multidrug resistance.

6. Lipid-PEGs

NSP offers a diverse range of lipid and phospholipid PEG derivatives for applications in drug delivery, liposome and micelle formation, formulation of small- and macromolecule therapeutics, and surface modification.

7. Poly(amino acid)-PEGs

NSP PEG-PAA products include poly(L-lysine)-PEG, poly(L-glutamic acid)-PEG, poly(L-aspartic acid)-PEG, and their functionalized copolymers. These materials support a variety of needs in delivery system design and biomaterial research.

8. Functional PEGs

NSP provides a wide range of high-quality PEG reagents for PEGylation, drug delivery, bioconjugation, and surface modification. Its functional PEG portfolio includes monofunctional PEGs, homobifunctional PEGs, heterobifunctional PEGs, and multi-arm PEGs.

materials support a variety of needs in delivery system design and biomaterial research.

9. Monomers

Monomers are molecules that can be linked with other molecules through chemical or supramolecular approaches to form polymers or supramolecular polymer systems for advanced material design.

10. Polyester-PEGs

NSP offers polyester-based functional amphiphilic block copolymers for drug delivery research, including PLA-PEG, PLGA-PEG, and PCL-PEG. These materials are widely used in the development of delivery vehicles and nanoformulations.

11. Polymers by Functional Group

NSP classifies polymers by a wide range of functional groups, including but not limited to amino, Boc- or Fmoc-protected amino, carboxyl, maleimide, biotin, azide, thiol, hydrazide, alkyne, OPSS, NHS ester, vinyl sulfone, acrylate, NPC, DBCO, and folate groups. This classification supports flexible selection for conjugation, modification, and targeted application development.

12. Fluorescent Polymers

NSP offers ready-to-use fluorescent polymers that enable researchers to track polymers and nanomedicines using microscopy or IVIS imaging. Available fluorescent labels include rhodamine, fluorescein, Cy3, Cy5.0, Cy5.5, and Cy7.
