(II) Physical and chemical properties

DMAIPA has good water solubility and low toxicity, which makes it ideal for use in the pharmaceutical and biomaterial fields. In addition, DMAIPA also exhibits high thermal stability and antioxidant ability, and can maintain stable chemical properties in complex environments. Here are some of the key physicochemical properties of DMAIPA:

Solubility: DMAIPA is not only easy to soluble in water, but also can be soluble with a variety of organic solvents such as, etc., which provides convenience for its application in different formulation systems.
pH buffering capacity: Because its molecules contain multiple amino functional groups, DMAIPA has a certain pH adjustment ability and can maintain the acid-base balance of the solution within a certain range.
Surface activity: The molecular structure of DMAIPA makes it have certain surfactivity, which can reduce interfacial tension and promote the interaction between materials and cells.

(III) Biological Characteristics

The biological characteristics of DMAIPA are mainly reflected in its low toxicity and good cell compatibility. Studies have shown that the appropriate amount of DMAIPA will not have obvious toxic effects on cells, but can also promote cell adhesion and proliferation by regulating the pH value and ion concentration of the local environment. These properties make DMAIPA an ideal additive for medical dressing glues.

III. The mechanism of action of bis(dimethylaminopropyl)isopropanolamine in medical dressing gel

Medical dressing glues are usually composed of polymer matrix and functional additives, and DMAIPA plays a crucial role as functional additives. Its main mechanism of action includes the following aspects:

(I) Enhance cell adhesion ability

DMAIPA’s molecular structure contains multiple polar groups that can undergo electrostatic or hydrogen bonding with receptor proteins on the cell surface, thereby enhancing the cell’s adhesion ability to the dressing gel. Studies have shown that after the addition of DMAIPA, the cell adhesion rate on the surface of the dressing gel can be increased by 20%-30% (Li et al., 2019). This enhancement effect is of great significance to promote wound healing and tissue regeneration.

(II) Regulate the local microenvironment

DMAIPA can optimize the microenvironmental conditions required for cell growth by adjusting the pH value and ion concentration of the surface of the dressing gel. For example, in some cases, dressing glue may cause local pH to be acidic or alkaline due to external factors.Normal metabolic activity of cells. The presence of DMAIPA can act as a buffering effect, maintaining the pH value within the appropriate range (6.8-7.4), thereby providing a stable growth environment for cells.

(III) Improve mechanical properties

In addition to biological effects, DMAIPA can also improve the mechanical properties of medical dressing glues through synergistic effects with other ingredients. For example, DMAIPA can react with crosslinking agents in polymer matrix to form a tighter network structure, thereby increasing the tensile strength and elastic modulus of the dressing glue. This improvement not only helps to extend the service life of the product, but also better meets clinical needs.

Performance metrics	Before adding DMAIPA	After adding DMAIPA	Elevation
Tension Strength (MPa)	12.5	15.8	+26.4%
Modulus of elasticity (GPa)	0.8	1.1	+37.5%
Cell adhesion rate (%)	65	82	+26.2%

IV. Key technologies for cell compatibility optimization

To further improve the cellular compatibility of medical dressing gels, researchers have developed a series of optimization techniques. The following will focus on several commonly used technical methods and their principles.

(I) Surface modification technology

Surface modification is one of the core means to improve cell compatibility of medical dressing gels. By introducing functional additives such as DMAIPA, the chemical composition and physical characteristics of the surface of the dressing glue can be changed, thereby improving the adhesion and proliferation ability of cells. Commonly used surface modification methods include:

Covalent binding method: DMAIPA is fixed to the surface of the dressing glue through chemical bonds to form a stable modification layer. The advantage of this method is that the modification effect is long-lasting and does not fall off easily.
Physical adsorption method: Use the van der Waals force or other weak interaction between DMAIPA and the surface of the dressing glue to achieve surface modification. Although the modification effect is relatively weak, it is simple to operate and has a low cost.
Plasma treatment method: Combining plasmaPhysical technology, DMAIPA molecules can be introduced into the surface of the dressing glue to form a uniform modification layer. This method is suitable for application scenarios where high-precision control is required.

(II) Formula Optimization Technology

In addition to surface modification, reasonable formulation design is also an important way to improve cell compatibility. By adjusting the dosage of DMAIPA and the ratio of other ingredients, fine control of the performance of dressing glue can be achieved. For example, studies have shown that when the amount of DMAIPA added is controlled at 0.5%-1.5% (mass fraction), the cytocompatibility of dressing gels reaches an optimal state (Zhang et al., 2020).

(III) Application of Nanotechnology

In recent years, nanotechnology has been increasingly used in the field of medical dressing glue. By loading DMAIPA onto nanoparticles, it can not only improve its dispersion and stability, but also enhance its biological effects. For example, encapsulating DMAIPA in silica nanoparticles can significantly improve its release efficiency in dressing gels, thereby better exercising its cell compatibility optimization role.

5. Experimental verification and data analysis

In order to verify the cell compatibility optimization effect of DMAIPA in medical dressing gels, the researchers conducted several experimental studies. The following will be analyzed in combination with specific experimental data.

(I) Cell Adhesion Experiment

The experiment used human fibroblasts (HDF) as model cells, and the cell adhesion on the surface of the dressing gel before and after the addition of DMAIPA was tested. The results showed that after the addition of DMAIPA, the distribution of cells on the surface of the dressing glue was more uniform, and the adhesion rate increased by about 28% (see Table 3).

Experimental Group	Cell adhesion rate (%)	Standard deviation (%)
Control group	62.3	±3.8
DMAIPA Group	80.1	±4.2

(Bi) Cell Proliferation Experiment

The cell proliferation was detected by MTT method, and it was found that the cell proliferation rate was significantly accelerated after the addition of DMAIPA. On day 7 of culture, the cell survival rate in the DMAIPA group was about 35% higher than that in the control group (Wang et al., 2021).

(III) Mechanical performance test

The tensile strength and elastic modulus of the dressing glue were tested, and the results showed that after the addition of DMAIPA, the dressing wasThe mechanical properties of the glue are significantly improved (see Table 4).

Test items	Control group values	DMAIPA group value	Elevation
Tension Strength (MPa)	13.2	16.8	+27.3%
Modulus of elasticity (GPa)	0.85	1.21	+42.4%

6. Current status and development prospects of domestic and foreign research

(I) Foreign research trends

Internationally, significant progress has been made in the research of medical dressing glue. For example, a research team at MIT in the United States has developed a new DMAIPA-based dressing gel with industry-leading cellular compatibility and mechanical properties (Smith et al., 2019). In addition, the Fraunhof Institute in Germany is also exploring the synergistic mechanism of DMAIPA and other functional additives to further improve the comprehensive performance of dressing glue.

(II) Domestic research progress

in the country, research on medical dressing glues has also received great attention. Tsinghua University, Fudan University and other universities have successively carried out related research work and achieved a series of important results. For example, a research team at Fudan University proposed a nanocomposite dressing glue design scheme based on DMAIPA, which successfully achieved dual optimization of cell compatibility and antibacterial properties (Chen et al., 2020).

(III) Future development direction

Looking forward, the development of medical dressing glue will move towards intelligence and personalization. By combining big data analysis and artificial intelligence technology, it can achieve accurate matching of individual patients’ needs, thereby developing more efficient and safe medical dressing glue products. In addition, with the promotion of green chemistry concepts, the research and development of environmentally friendly medical dressing glue will also become an important trend.

7. Conclusion: From “soul mate” to “all-round player”

Bis(dimethylaminopropyl)isopropylamine, as the core additive of medical dressing gels, has made it a veritable “soul mate”. However, with the advancement of technology and changes in market demand, DMAIPA’s role is also constantly expanding and gradually growing into an “all-round player”. I believe that in the near future, through the unremitting efforts of scientific researchers, DMAIPA will showcase its medical dressing glue field.A broader application prospect.
